Found using the vet check in CL 106370045.
This is a second attempt at CL 101670044, which omitted the deps_test change.
This adds dependencies to net/rpc:
encoding
encoding/base64
encoding/json
html
unicode/utf16
The obvious correctness and security warrants the additional dependencies.

When we've switched to 8K pages,
heap started to grow by 128K instead of 64K,
because it was implicitly assuming that pages are 4K.
Fix that and make the code more robust.

size instead of abusing text symbol
cmd/addr2line needs to know the virtual address of the start
of the text segment (load address plus header size). For
this, it used the text symbol added by the linker. This is
wrong on amd64. Header size is 40 bytes, not 32 like on 386
and arm. Function alignment is 16 bytes causing text to be
at 0x200030.
debug/plan9obj now exports both the load address and the
header size; cmd/addr2line uses this new information and
doesn't rely on text anymore.

NetlinkRIB is currently allocating a page sized slice of bytes in a
for loop and it's also calling Getpagesize() in the same for loop.
This CL changes NetlinkRIB to preallocate the page sized slice of
bytes before reaching the for loop. This reduces memory allocations
and lowers the number of calls to Getpagesize() to 1 per NetlinkRIB
call.
This CL reduces the allocated memory from 141.5 MB down to 52 MB in
a test.

Fixes#8165.
After this change, the panic is replaced by a message:
$ go build -o out ...doesntexist
warning: "...doesntexist" matched no packages
no packages to build
The motivation to return 1 exit error code is to allow -o flag
to be used to guarantee that the output binary is written to
when exit status is 0. If someone uses an import path pattern
to specify a single package and suddenly that matches no packages,
it's better to return exit code 1 instead of silently doing nothing.
This is consistent with the case when -o flag is given and multiple
packages are matched.
It's also somewhat consistent with the current behavior with the
panic, except that gave return code 2. But it's similar in
that it's also non-zero (indicating failure).
I've changed the language to be similar to output of go test
when an import path pattern matches no packages (it also has a return status of
1):
$ go test ...doesntexist
warning: "...doesntexist" matched no packages
no packages to test

The code generating the .debug_frame section emits pairs of "advance PC",
"set SP offset" pseudo-instructions. Before the fix, the PC advance comes
out before the SP setting, which means the emitted offset for a block is
actually the value at the end of the block, which is incorrect for the
block itself.
The easiest way to fix this problem is to emit the SP offset before the
PC advance.
One delicate point: the last instruction to come out is now an
"advance PC", which means that if there are padding intsructions after
the final RET, they will appear to have a non-zero offset. This is odd
but harmless because there is no legal way to have a PC in that range,
or to put it another way, if you get here the SP is certainly screwed up
so getting the wrong (virtual) frame pointer is the least of your worries.

Based on cl/69170045 by Elias Naur.
There are currently several schemes for acquiring a TLS
slot to save the g register. None of them appear to work
for android. The closest are linux and darwin.
Linux uses a linker TLS relocation. This is not supported
by the android linker.
Darwin uses a fixed offset, and calls pthread_key_create
until it gets the slot it wants. As the runtime loads
late in the android process lifecycle, after an
arbitrary number of other libraries, we cannot rely on
any particular slot being available.
So we call pthread_key_create, take the first slot we are
given, and put it in runtime.tlsg, which we turn into a
regular variable in cmd/ld.
Makes android/arm cgo binaries work.

The code in GC that handles gp->gobuf.ctxt is wrong,
because it does not mark the ctxt object itself,
if just queues the ctxt object for scanning.
So the ctxt object can be collected as garbage.
However, Gobuf.ctxt is void*, so it's always marked and
scanned through G.
