Alexey Borzenkov 0669261af1 cmd/dist: don't fail when Mercurial is a batch file on Windows
On windows Mercurial installed with easy_install typically creates
an hg.bat batch file in Python Scripts directory, which cannot be used
with CreateProcess unless full path is specified. Work around by
launching hg via cmd.exe /c.

Additionally, fix a rare FormatMessageW crash.

Fixes #3093.

FTR, below are result with the empty prefetch function,
that is, single RET but no real prefetching.
It suggests that inlinable PREFETCH is worth pursuing.

Bobby Powers c9529e02c1 time: in Format give buffer an initial capacity
I have a small web server that simply sets several cookies
along with an expires header, and then returns.  In the
cpuprofile for a 200k request benchmark, time.Time.Format()
was showing up as 8.3% of cpu usage.  Giving the buffer an
inital capacity to avoid reallocs on append drops it down to
7.6%.

Building go currently fails on NetBSD, thus the regeneration

the go_bootstrap tool builds correctly.

Previously we checked that de ≡ 1 mod φ(n). Since φ(n) is a multiple
of |(ℤ/nℤ)*|, this encompassed the new check, but it was too strict as
keys generated by GnuTLS would be rejected when gcd(p-1,q-1)≠1.

(Also updated the error strings in crypto/rsa to contain the package name, which some were missing.)

Russ Cox 5eb007dede runtime: work around false negative in deadlock detection
Not a complete fix for issue 3342, but fixes the trivial case.
There may still be a race in the instants before and after
a scavenger-induced garbage collection.

Intended to be "obviously safe": a call to runtime·gosched
before main.main is no different than a call to runtime.Gosched
at the beginning of main.main, and it is (or had better be)
safe to call runtime.Gosched at any point during main.

Russ Cox 9d7076b178 cmd/go: respect $GOBIN always
Another attempt at https://golang.org/cl/5754088.

Before, we only consulted $GOBIN for source code
found in $GOROOT, but that's confusing to explain
and less useful.  The new behavior lets users set
GOBIN=$HOME/bin and have all go-compiled binaries
installed there.

Tested a few cases in test.bash.

Ran all.bash with and without $GOBIN and it works.
Even so, I expect it to break the builders,
like it did last time, we can debug from there.

Fixes #3269 (again).
Fixes #3396.
Fixes #3397.

Russ Cox 671862747e go/build: fix import check
When we find a package in DIR/src/foo, we only let it
be known as foo if there is no other foo in an earlier
GOPATH directory or the GOROOT directory.
The GOROOT check was looking in GOROOT/src/foo
instead of GOROOT/src/pkg/foo, which meant that
the import paths "lib9", "libbio", "libmach", and so
on were unavailable, and the import paths "math",
"errors", and so on were available.  Correct this.

Fixes #3390.

Russ Cox 6b0929505b cmd/go: fix two bugs
Issue 3207 was caused by setting GOPATH=GOROOT.
This is a common mistake, so diagnose it at command start
and also correct the bug that it caused in get (downloading
to GOROOT/src/foo instead of GOROOT/src/pkg/foo).

Issue 3268 was caused by recognizing 'packages' that
had installed binaries but no source.  This behavior is not
documented and causes trouble, so remove it.  We can
revisit the concept of binary-only packages after Go 1.

Fixes #3207.
