428c349552 cmd/link, cmd/internal/obj: give Headtype a type
Separate out windows/windowsgui properly so we are not encoding some
of the Headtype value in a separate headstring global.

Remove one of the two copies of the variable from cmd/link.

Remove duplicate string to headtype list.

39382793d3 context: reduce memory usage of context tree
Modifies context package to use map[]struct{} rather than map[]bool,
since the map is intended as a set object.  Also adds Benchmarks to
the context package switching between different types of root nodes
and a tree with different depths.

Included below are bytes deltas between the old and new code, using
these benchmarks.

0ab6bb42e1 doc: clarify that any C compiler works for cgo
Currently the footnote says "gcc is required only if you plan to use cgo",
but the footnote was referenced from the text:

   "use the clang or gcc† that comes with Xcode‡ for cgo support"

That seems to imply that clang doesn't get you cgo support on OS X,
which isn't true. The update text matches what the install-source.html
page says.

It is better to document what golang does, rather than how it differs
from languages which readers may or may not know.

That the output format is based on the type is basically self-evident
if you consider this just in go terms.

f27c1bda51 net/url: handle escaped paths in ResolveReference
Currently, path resolution is done using the un-escaped version of
paths. This means that path elements like one%2ftwo%2fthree are
handled incorrectly, and optional encodings (%2d vs. -) are dropped.

This function makes escaped handling consistent with Parse: provided
escapings are honoured, and RawPath is only set if necessary.

A helper method setPath is introduced to handle the correct setting of
Path and RawPath given the encoded path.

Fixes #16947

ed8f207940 encoding/json: Use a lookup table for safe characters
The previous check for characters inside of a JSON string that needed
to be escaped performed seven different boolean comparisons before
determining that a ASCII character did not need to be escaped. Most
characters do not need to be escaped, so this check can be done in a
more performant way.

Use the same strategy as the unicode package for precomputing a range
of characters that need to be escaped, then do a single lookup into a
character array to determine whether the character needs escaping.

For what it's worth, I tried other heuristics - short circuiting the
conditional for common ASCII characters, for example:

if (b >= 63 && b != 92) || (b >= 39 && b <= 59) || (rest of the conditional)

This offered a speedup around 7-9%, not as large as the submitted
change.

252093f120 runtime: remove maxstring
Before this CL the runtime prevented printing of overlong strings with the print
function when the length of the string was determined to be corrupted.
Corruption was checked by comparing the string size against the limit
which was stored in maxstring.

However maxstring was not updated everywhere were go strings were created
e.g. for string constants during compile time. Thereby the check for maximum
string length prevented the printing of some valid strings.

The protection maxstring provided did not warrant the bookkeeping
and global synchronization needed to keep maxstring updated to the
correct limit everywhere.

3ef0e8f823 net: remove parsing of negative decimals in IPv4 literal
https://golang.org/cl/27206 fixed the dtoi function such that
it now properly parses negative number. Ironically, this causes
several other functions that depended on dtoi to now (incorrectly)
parse negative numbers.

For example, ParseCIDR("-1.0.0.0/32") used to be rejected prior to the
above CL, but is now accepted even though it is an invalid CIDR notation.
This CL fixes that regression.

We fix this by removing the signed parsing logic entirely from dtoi.
It was introduced relatively recently in https://golang.org/cl/12447
to fix a bug where an invalid port was improperly being parsed as OK.
It seems to me that the fix in that CL to the port handling logic was
sufficient such that a change to dtoi was unnecessary.

42433e27b0 cmd/compile: add format verification test
TestFormats finds potential (Printf, etc.) format strings.
If they are used in a call, the format verbs are verified
based on the matching argument type against a precomputed
table of valid formats (formatMapping, below). The table
can be used to automatically rewrite format strings with
the -u flag.

Run as: go test -run Formats [-u]

A formatMapping based on the existing formats is printed
when the test is run in verbose mode (-v flag). The table
needs to be updated whenever a new (type, format) combination
is found and the format verb is not 'v' (as in "%v").

Known bugs:
- indexed format strings ("%[2]s", etc.) are not suported
  (the test will fail)
- format strings that are not simple string literals cannot
  be updated automatically
  (the test will fail with respective warnings)

238274df4e go/constant: document that Value.String and ExactString return quoted strings
This has always been the case but it was not obvious from the documentation.
The reason for the quoting is that String() may return an abbreviated string,
starting with double-quote (") but ending in ... (w/o a quote). The missing
quote indicates the abbreviation (in contrast to a string ending in ...").

constant.StringVal can be used to obtain the unquoted string of a String Value.
