4b38200bfd cmd/go: correctly quote environment variables in -x output
This fixes the -x output so that when it reports environment variables they
are correctly quoted for later execution by the shell.
Also fix -x output to use the right path to the pack tool, and note when
we are touching a file.

Fixes #21427

90ffc40e4f cmd/link: correct Mach-O file flag
Only set MH_NOUNDEFS if there are no undefined symbols.
Doesn't seem to matter, but may as well do it right.

f4abbc0e61 cmd/link,compile: Provide size for func types
They are currently not given a size, which makes the DWARF reader
very confused. Particularly things like [4]func() get a size of -4, not 32.

77a9cb9b4c runtime: refactor evacuate x/y handling
This change unifies the x and y cases.

It shrinks evacuate's machine code by ~25% and its stack size by ~15%.

It also eliminates a critical branch.
Whether an entry should go to x or y is designed to be unpredictable.
As a result, half of the branch predictions for useX were wrong.
Mispredicting that branch can easily incur an expensive cache miss.
Switching to an xy array allows elimination of that branch,
which in turn reduces cache misses.

589fc314af runtime: calculate k only once in mapiternext
Make the calculation of k and v a bit lazier.
None of the following code cares about indirect-vs-direct k,
and it happens on all code paths, so check t.indirectkey earlier.

Simplifies the code and reduces both machine code and stack size.

694875cbf2 archive/tar: remove writeHeader and writePAXHeaderLegacy
Previous CLs (CL/54970, CL55231, and CL/55237) re-implemented tar.Writer
entirely using specialized methods (writeUSTARHeader, writePAXHeader,
and writeGNUHeader) allowing tar.Writer to entirely side-step the broken
and buggy logic in writeHeader.

Since writeHeader and writePAXHeaderLegacy is now dead-code,
we can delete them.

One minor change is that we call Writer.Flush at the start of WriteHeader.
This used to be performed by writeHeader, but doing so in WriteHeader
ensures each of the specialized methods can benefit from its effect.

Fixes #17665
Fixes #12594

ffd9810e59 archive/tar: implement specialized logic for GNU format
Rather than going through writeHeader, which attempts to handle all formats,
implement writeGNUHeader, which only has an understanding of the GNU format.

Currently, the implementation is nearly identical to writeUSTARHeader, except:
* formatNumeric is used instead of formatOctal
* the GNU magic value is used

This is kept as a separate method since it makes more logical sense
when we add support for sparse files, long filenames, and atime/ctime fields,
which do not affect USTAR.

Updates #12594

7ae9561610 archive/tar: implement specialized logic for PAX format
Rather than going through writeHeader, which attempts to handle all formats,
implement writePAXHeader, which only has an understanding of the PAX format.

In PAX, the USTAR header is filled out in a best-effort manner.
Thus, we change logic of formatString and formatOctal to try their best to
output something (possibly truncated) in the event of an error.

The new implementation of PAX headers causes several tests to fail.
An investigation into the new output reveals that the new behavior is correct,
while the tests had actually locked in incorrect behavior before.

A dump of the differences is listed below (-before, +after):

<< writer-big.tar >>

This change is due to fact that we changed the Header.Devminor to force the
tar.Writer to choose the GNU format over the PAX one.
The ability to control the output is an open issue (see #18710).
- 00000150  00 30 30 30 30 30 30 30  00 00 00 00 00 00 00 00  |.0000000........|
+ 00000150  00 ff ff ff ff ff ff ff  ff 00 00 00 00 00 00 00  |................|

<< writer-big-long.tar>>

The previous logic generated the GNU magic values for a PAX file.
The new logic correctly uses the USTAR magic values.
- 00000100  00 75 73 74 61 72 20 20  00 00 00 00 00 00 00 00  |.ustar  ........|

The previous logic tried to use the specified timestmap in the PAX headers file,
but this is problematic as this timestamp can overflow, defeating the point
of using PAX, which is intended to extend tar.
The new logic uses the zero timestamp similar to what GNU and BSD tar do.
- 00000080  30 30 30 30 32 33 32 00  31 32 33 33 32 37 37 30  |0000232.12332770|

The previous logic populated the devminor and devmajor fields.
The new logic leaves them zeroed just like what GNU and BSD tar do.

The previous logic uses PAX headers, but fails to add a record for the size.
The new logic does properly add a record for the size.
- 00000290  31 36 67 69 67 2e 74 78  74 0a 00 00 00 00 00 00  |16gig.txt.......|

The previous logic encoded the size as a base-256 field,
which is only valid in GNU, but the previous PAX headers implies this should
be a PAX file. This result in a strange hybrid that is neither GNU nor PAX.
The new logic uses PAX headers to store the size.

The tests for error scenarios were done by manually checking

instead of just the string.

Printing the actual error in case of failure instead of a
generic string.

Also added a new scenario with both an invalid byte and an
invalid length string to verify that the length is checked first
before doing any computation.

5d14ac74f6 encoding/csv: report line start line in errors
Errors returned by Reader contain the line where the Reader originally
encountered the error. This can be suboptimal since that line does not
always correspond with the line the current record/field started at.

This can easily happen with LazyQuotes as seen in #19019, but also
happens for example when a quoted fields has no closing quote and
the parser hits EOF before it finds another quote.

When this happens finding the erroneous field can be somewhat
complicated and time consuming, and in most cases it would be better to
report the line where the record started.

This change updates Reader to keep track of the line on which a record
begins and uses it for errors instead of the current line, making it
easier to find errors.

Although a user-visible change, this should have no impact on existing
code, since most users don't explicitly work with the line in the error
and probably already expect the new behaviour.

Updates #19019

67c360594f syscall: add utimensat and use it for UtimesNano on BSD and Solaris
All the BSDs and Solaris support the utimensat syscall, but Darwin
doesn't. Account for that by adding the //sys lines not to
syscall_bsd.go but the individual OS's syscall_*.go files and implement
utimensat on Darwin as just returning ENOSYS, such that UtimesNano will
fall back to use utimes as it currently does unconditionally.

This also adds the previously missing utimensat syscall number for
FreeBSD and Dragonfly.

Fixes #16480

f5804ce4f3 runtime: simplify hashmap tooManyOverflowBuckets
This generates better code.

Masking B in the return statement should be unnecessary,
but the compiler is understandably not yet clever enough to see that.

Someday, it'd also be nice for the compiler to generate
a CMOV for the saturation if statement.

9065c3bf34 runtime: support DT_GNU_HASH in VDSO
Currently we only support finding symbols in the VDSO using the old
DT_HASH. These days everything uses DT_GNU_HASH instead. To keep up
with the times and future-proof against DT_HASH disappearing from the
VDSO in the future, this commit adds support for DT_GNU_HASH and
prefers it over DT_HASH.

Tested by making sure it found a DT_GNU_HASH section and all of the
expected symbols in it, and then disabling the DT_GNU_HASH path and
making sure the old DT_HASH path still found all of the symbols.

Fixes #19649.

fee7f2ab16 strings: speed up FieldsFunc
Increases performance of FieldsFunc by recording the start and end
of the fields in an array. The first 32 fields are saved in a pre-allocated
array on the stack. This avoids the old behavior of iterating over the
input string two times but uses more allocations when more than 32 fields
are encountered.

Additionally code for handling non-ASCII containing strings from Fields is
removed and replaced by a call to the new faster FieldsFunc function.

Overall this still leads to a slowdown for Fields on non-ASCII strings
while speeding up Fields in general.

fc6b74ce39 strconv: fix ParseUint return value on range overflow
If the value corresponding to the input string cannot be

err.Err = ErrRange and the returned value is the maximum
magnitude unsigned integer of the appropriate bitSize.
This is consistent with ParseInt's behavior and the documentation.

Expand tests to test 32 bit test value tables with bitsize 32 set.
These tests fail without the fix in this CL.
