00bfb3ab44 tree: Fix various typos and outdated terminology
This was mostly machine generated with the following command:
```
codespell \
    --builtin clear,rare,usage \
    --skip './po/*' --skip './.git/*' --skip './NEWS*' \
    --write-changes .
```
using the latest git version of `codespell` as per [these
instructions](https://github.com/codespell-project/codespell#user-content-updating).

Then I manually checked each change using `git add -p`, made a few
manual fixups and dropped a load of incorrect changes.

There are still some outdated or loaded terms used in GLib, mostly to do
with git branch terminology. They will need to be changed later as part
of a wider migration of git terminology.

If I’ve missed anything, please file an issue!

7f256e63d0 tests: Fix small race in GSubprocess tests
This was introduced in commit 7846d6154a: g_subprocess_get_identifier()
will return NULL after the subprocess has exited, and the subprocess in
the `noop` test will exit as soon as it has started spawning. So if the
scheduler scheduled the testprog subprocess quickly, descheduled the
parent test process until the testprog exited, then the return value
from g_subprocess_get_identifier() would be NULL.

Move the g_subprocess_get_identifier() test to one which calls testprog
in `sleep-forever` mode, since that is guaranteed not to exit until
killed (which we do later in the test).

277c42ddc0 tests: Convert g_assert() to g_assert_*() in gio/tests/gsubprocess.c

out when building with G_DISABLE_ASSERT.

1cc78bf082 GSubprocess test: Adjust the cwd test to pass on Windows
There's no /tmp directory on Windows.
Use g_get_tmp_dir(), and adjust the test to work with that.
The test *still* checks the basename of the new CWD, it just
doesn't need to be "tmp" anymore.

4bc1aa23a9 GSubprocess test: Add PATH to the envtable that is passed to child
envp in spawn() functions is the *whole* environment table
for the child process. Including PATH. Thus, unless PATH is explicitly
put into that table, the process will be spawned without PATH.
Since on Windows binaries are found via PATH instead of LD_LIBRARY_PATH
or whatever, almost no program (unless installed in WINDIR, maybe)
can run without a PATH. Certainly not test programs - meson
adds bld subdirs to the PATH to make sure that test programs
use uninstalled glib at runtime.
So make sure that PATH is passed along.

01642d6db5 GSubprocess test: Use LINEEND more
Windows \r\n EOLs strike again. The test already knows about LINEEND,
so make it use LINEEND more (instead of swithcing pipes
to binary mode). This also applies to counting the bytes
read.

19c7a7bb23 gsubprocess: Add a missing test for invalid UTF-8 output
There were tests for invalid UTF-8 output when asynchronously
communicating with a subprocess, but nothing for synchronous
communication. Add such a test, and refine the code as a result.

66ab836f5a gsubprocess: Fix a critical calling communicate() with no pipes
If calling g_subprocess_communicate() on a GSubprocess with no
stdout/stderr pipe, a critical warning would be emitted from
g_memory_output_stream_steal_as_bytes(), as it would be called on a NULL
output stream.

Fix that, improve the relevant GIR annotations, and expand the unit
tests to cover it (and various other combinations of flags).

e1e73dafa6 gsubprocess: Copy parent process’ environ when clearing subprocess’
Previously, this was done at the time of spawning the subprocess, which
meant the g_subprocess_launcher_*_environ() functions could not be used
to modify the parent process’ environment.

Change the code to copy the parent process’ environment when
g_subprocess_launcher_set_environ(NULL) is called. Document the change
and add a unit test.

c9ccc2af91 gio/tests: Add non-NULL assertions to help static analysis
These prevent some false positives from the static analyser which are
caused by it not inspecting the invariants of
g_subprocess_communicate[_utf8]_finish() (i.e. that stdout and
stdout_str will always be set unless an error was returned).

They’re also good testing anyway.

b27a2d436b gio/tests/gsubprocess.c: Fix on Windows
We need to check for the correct line endings on Windows (\r\n) for the
echo tests and currently need to skip the test_echo_eof test there, as
it depends on the cat utility that is not normally found on Windows, and
using an external installation of cat via MSYS or Cygwin would render the
test program to hang as cat waits for user input.

9318d5a429 gsubprocess: Add UTF-8 variants of communicate()
Over many years of writing code interacting with subprocesses, a pattern
that comes up a lot is to run a child and get its output as UTF-8, to
put inside a JSON document or render in a GtkTextBuffer, etc.

It's very important to validate at the boundaries, and not say deep
inside Pango.

We could do this a bit more efficiently if done in a streaming fashion,
but realistically this should be OK for now.

0e1a3ee345 gsubprocess: Fix up communicate
We weren't closing the streams after we were done reading or writing,
which is kind of essential.  The easy way to fix this is to just use
g_output_stream_splice() to a GMemoryOutputStream rather than
hand-rolling it.  This results in a substantial reduction of code
complexity.

A second serious issue is that we were marking the task as complete when
the process exits, but that's racy - there could still be data to read
from stdout.  Fix this by just refcounting outstanding operations.

This code, not surprisingly, looks a lot like the "multi" test.

Next, because processes output binary data, I'd be forced to annotate
the char*/length pairs as (array) (element-type uint8).  But rather than
doing that, it's *far* simpler to just use GBytes.

We need a version of this that actually validates as UTF-8, that will be
in the next patch.

5b48dc40cc GSubprocess: New class for spawning child processes
There are a number of nice things this class brings:

0) Has a race-free termination API on all platforms (on UNIX, calls to
   kill() and waitpid() are coordinated as not to cause problems).
1) Operates in terms of G{Input,Output}Stream, not file descriptors
2) Standard GIO-style async API for wait() with cancellation
3) Makes some simple cases easy, like synchronously spawning a
   process with an argument list
4) Makes hard cases possible, like asynchronously running a process
   with stdout/stderr merged, output directly to a file path

Much rewriting and code review from Ryan Lortie <desrt@desrt.ca>
