e463c28cc1 cmd/link: avoid exporting all symbols on windows buildmode=pie
Marking one functions with __declspec(dllexport) forces mingw to
create .reloc section without having to export all symbols.

See https://insights.sei.cmu.edu/cert/2018/08/when-aslr-is-not-really-aslr---the-case-of-incorrect-assumptions-and-bad-defaults.html for more info.

6f7b553c82 cmd/cgo: avoid exporting all symbols on windows buildmode=c-shared
Disable default symbol auto-export behaviour by marking exported
function with the __declspec(dllexport) attribute. Old behaviour can
still be used by setting -extldflags=-Wl,--export-all-symbols.

a413908dd0 all: add GOOS=ios
Introduce GOOS=ios for iOS systems. GOOS=ios matches "darwin"
build tag, like GOOS=android matches "linux" and GOOS=illumos
matches "solaris". Only ios/arm64 is supported (ios/amd64 is
not).

GOOS=ios and GOOS=darwin remain essentially the same at this
point. They will diverge at later time, to differentiate macOS
and iOS.

Uses of GOOS=="darwin" are changed to (GOOS=="darwin" || GOOS=="ios"),
except if it clearly means macOS (e.g. GOOS=="darwin" && GOARCH=="amd64"),
it remains GOOS=="darwin".

Updates #38485.

3922c006ad misc/cgo/testcshared: avoid writing to GOROOT in tests
The tests in this package invoked 'go install -i -buildmode=c-shared'
in order to generate an archive as well as multiple C header files.

Unfortunately, the behavior of the '-i' flag is inappropriately broad
for this use-case: it not only generates the library and header files
(as desired), but also attempts to install a number of (unnecessary)
archive files for transitive dependencies to
GOROOT/pkg/$GOOS_$GOARCH_testcshared_shared, which may not be writable
— for example, if GOROOT is owned by the root user but the test is
being run by a non-root user.

Instead, for now we generate the header files for transitive dependencies
separately by running 'go tool cgo -exportheader'.

In the future, we should consider how to improve the ergonomics for
generating transitive header files without coupling that to
unnecessary library installation.

8f70e1f8a9 cmd/go: do not install dependencies during "go install"
This CL makes "go install" behave the way many users expect:
install only the things named on the command line.
Future builds still run as fast, thanks to the new build cache (CL 75473).
To install dependencies as well (the old behavior), use "go install -i".

Actual definitions aside, what most users know and expect of "go install"
is that (1) it installs what you asked, and (2) it's fast, unlike "go build".
It was fast because it installed dependencies, but installing dependencies
confused users repeatedly (see for example #5065, #6424, #10998, #12329,
"go build" and "go test" so that they could be "fast" too, but that only
created new opportunities for confusion. We also had to add -installsuffix
and then -pkgdir, to allow "fast" even when dependencies could not be
installed in the usual place.

The recent introduction of precise content-based staleness logic means that
the go command detects the need for rebuilding packages more often than it
used to, with the consequence that "go install" rebuilds and reinstalls
dependencies more than it used to. This will create more new opportunities
for confusion and will certainly lead to more issues filed like the ones
listed above.

CL 75743 introduced a build cache, separate from the install locations.
That cache makes all operations equally incremental and fast, whether or
not the operation is "install" or "build", and whether or not "-i" is used.

Installing dependencies is no longer necessary for speed, it has confused
users in the past, and the more accurate rebuilds mean that it will confuse
users even more often in the future. This CL aims to end all that confusion
by not installing dependencies by default.

By analogy with "go build -i" and "go test -i", which still install
dependencies, this CL introduces "go install -i", which installs
dependencies in addition to the things named on the command line.

Fixes #5065.
Fixes #6424.
Fixes #10998.
Fixes #12329.
Fixes #18981.
Fixes #22469.

Another step toward #4719.
