Brad Fitzpatrick 740e589bd0 html: lazily populate Unescape tables
Saves ~105KB of heap for callers who don't use html.UnescapeString.
(EscapeString is much more common).

Also saves 70KB of binary size, because now the linker can do dead
code elimination. (because #2559 is still open and global maps always
generate init code)

Fixes #26727
Updates #6853

Kir Kolyshkin 6bea321ba2 cmd/cgo: add column number to line directives
Due to a new specification of //line: directives, missing
column info is now treated as column 0, aka "unknown column"
(see https://github.com/golang/go/issues/24183 for details).

As cgo does not add column number to generated //line: directive,
resulting files parsed do not have column info.

Fix by adding column of 1 to generated line directives.

Keith Randall 344d0e0bf7 cmd/cgo: make sure we FinishType everything
Ensure that we call FinishType on all the types added to the ptrs map.
We only add a key to ptrKeys once. Once we FinishType for that key,
we'll never look at that key again. But we can add a new type under that
key later, and we'll never finish it.

Make sure we add the key to the ptrKeys list every time we make the list
of types for that key non-empty.

This makes sure we FinishType each pointer type exactly once.

Richard Musiol 9e2a4f4dff syscall: remove support for O_NONBLOCK and O_SYNC on js/wasm
This commit removes O_NONBLOCK on js/wasm. O_SYNC can't be
removed, because it is referenced by the os package, so instead
its use returns an error.

On Windows, the options O_NONBLOCK and O_SYNC are not available
when opening a file with Node.js. This caused the initialization
of the syscall package to panic.

The simplest solution is to not support these two options on js/wasm
at all. Code written for js/wasm is supposed to be portable,
so platform-specific options should not be used.

Fixes #26524.

Russ Cox f85125345c go/build: invoke go command to find modules during Import, Context.Import
The introduction of modules has broken (intentionally) the rule
that the source code for a package x/y/z is in GOPATH/src/x/y/z
(or GOROOT/src/x/y/z). This breaks the code in go/build.Import,
which uses that rule to find the directory for a package.

In the long term, the fix is to move programs that load packages
off of go/build and onto golang.org/x/tools/go/packages, which
we hope will eventually become go/packages. That code invokes
the go command to learn what it needs to know about where
packages are.

In the short term, though, there are lots of programs that use go/build
and will not be able to find code in module dependencies.
To help those programs, go/build now runs the go command to
ask where a package's source code can be found, if it sees that
modules are in use. (If modules are not in use, it falls back to the
usual lookup code and does not invoke the go command, so that
existing uses are unaffected and not slowed down.)

Helps #24661.

The Linux kernel faccessat system call does not take a flags parameter.
The flag parameter to the C library faccessat function is implemented in C.
The syscall.Faccessat function takes a flags parameter. In older releases
we have passed the flags parameter to the kernel, which ignored it.
In CL 120015 we started returning an error if any flags were set.
That seems clearly better than ignoring them, but it turns out that some
code was using the flags. The code was previously subtly broken.
Now it is obviously broken. That is better, but we can do better still:
we can implement the flags as the C library does. That is what this CL does.

Ian Lance Taylor ead59f4bf3 cmd/cgo: don't resolve typedefs in -godefs mode
In -godefs mode any typedefs that appear in struct fields and the like
will presumably be defined in the input file. If we resolve to the
base type, those cross-references will not work. So for -godefs mode,
keep the Go 1.10 behavior and don't resolve the typedefs in a loop.

Daniel Martí b39fb9ec85 cmd/go/internal/par: fix TestWorkParallel retries
When the test retried multiple times, it reused the same Work variable,
causing in the builders being flaky due to panics. I was able to
immediately reproduce the failure with stress and -race:

	$ go test -race -c && stress -p 32 ./par.test -test.run=TestWorkParallel$

	/tmp/go-stress909062277
	--- FAIL: TestWorkParallel (0.07s)
	panic: par.Work.Do: already called Do [recovered]
		panic: par.Work.Do: already called Do

Instead, use a new Work variable at each retry. Now, the line above
seems to never fail. Of course, much higher 'stress -p' values will
still result in "does not seem to be parallel" test failures since the
machine lacks resources. But those are test failures, not panics.

Fixes #26642.

Minaev Mike e5b13401c6 crypto/tls: fix deadlock when Read and Close called concurrently
The existing implementation of TLS connection has a deadlock. It occurs
when client connects to TLS server and doesn't send data for
handshake, so server calls Close on this connection. This is because
server reads data under locked mutex, while Close method tries to
lock the same mutex.

Before this CL the user effectively has to guess at the expected
location of a binary-only package. While the location is normally
obvious ($GOPATH/pkg/GOOS_GOARCH/PATH/PKG.a) it is much less so when
building with options that implicitly add an -installsufix option.

Ian Lance Taylor c0e5485bd5 runtime: ignore GNU/Linux sigaction errors for signals 32 and 33
This avoids problems when running under QEMU. It seems that at least
some QEMU versions turn the sigaction implementation into a call to
the C library sigaction function. The C library function will reject
attempts to set the signal handler for signals 32 and 33. Ignore
errors in that case.
