`getenv()` doesn't work well on Windows, f.ex., it can't fetch env
vars set with `SetEnvironmentVariable()`. This also means that it
doesn't work at all when targeting UWP since that's the only way to
set env vars in that case.
This adds really basic validation that `GTimeZone` can successfully
parse a ‘slim’ format timezone file.

Helps: #2129
Since tzcode95f (1995), TZif files have had a trailing
TZ string, used for timestamps after the last transition.
This string is specified in Internet RFC 8536 section 3.3.
init_zone_from_iana_info has ignored this string, causing it
to mishandle timestamps past the year 2038. With zic's new -b
slim flag, init_zone_from_iana_info would even mishandle current
timestamps. Fix this by parsing the trailing TZ string and adding
its transitions.
Closes#2129
Time zone transition times can range from -167:59:59 through
+167:59:59, according to Internet RFC 8536 section 3.3.1;
this is an extension to POSIX. It is needed for proper
support of TZif version 3 files.
It's not clear to me why this argument was excluded in the first place,
and Dan doesn't remember either. At least for consistency with
unescape_string, add it.

g_task_set_name() was added in GLib 2.60, so only use it in the
overridden definition of g_task_set_source_tag() if the user has said
that they require GLib ≥ 2.60.

g_assert_true(), g_assert_cmpint(), and friends, can return to the
caller if test_nonfatal_assertions is set, but this is normally not the
case. In particular, for the purposes of static analysis, we
specifically don't want to assume that they might return. Clang has an
analyzer_noreturn attribute for this exact purpose, which conveniently
already has a macro in gmacros.h.

There is no guarantee that this function would not be called
concurrently. Particularly since flatpak_info_read was set to TRUE
before /.flatpak-info is actually read from disk, there is a potential
race where a second thread would return default values for the various
flags set from that file.

Correct an off-by-one error in hex_unescape_string()'s computation of
the output string length.
(Turned into a git-format patch by Philip Withnall. Original patch
submitted on the Debian bug tracker, bug#962912.)
It's safe to assume an escaped string doesn't contain embedded null bytes,
but raw memory buffers (as returned by getxattr()) require more care.
If the length of the data to be escaped is known, use that knowledge instead
of invoking strlen().

Creating 1000 threads with the default stack size of 8 MiB will fail on
architectures with a 32-bit address space. Move up the existing THREADS
macro and use that instead, but change its definition to 1000 if
pointers are larger than 32 bits.

A query string may have some '=' characters '%'-encoded that could be
split by g_uri_parse_params() incorrectly. Instead, callers should leave
the query part encoded, and let g_uri_parse_params() do the decoding.

This should give a bit more flexibility, without drawbacks.
Many URI encoding accept either '&' or ';' as separators.
Change the documentation to reflect that '&' is probably more
common (http query string).

gboolean is secretly actually typedef gint gboolean, so the delim_table
is going to take 1KB of stack all by itself. That’s fine, but it could
be smaller.
This strnpbrk()-like block could do with a comment to make it a bit
clearer what it’s doing.

And improve them externally, where not otherwise set, by setting them
from the function name passed to `g_task_set_source_tag()`, if called by
third party code.
This should make profiling and debug output from GLib more useful.

Use this to replace the much-hated `g_debug()` which told people that
`posix_spawn()` (the fast path) wasn’t being used for various reasons.
If people want to make their process spawning faster now, they’ll have
to use a profiling tool like sysprof to check their program’s
performance. Shocking.
I think I was wrong to put this `g_debug()` in there in the first place
— it hasn’t served its purpose of making people speed up their spawn
paths to use `posix_spawn()`, it’s only cluttered up logs and frustrated
people.

`complete_in_idle_cb()` shows up in a lot of sysprof traces, so it’s
quite useful to include the most specific contextual information we can
in it.
Signed-off-by: Philip Withnall <withnall@endlessm.com>
This allows you to see how long each `GMainContext` iteration and each
`GSource` `check`/`prepare`/`dispatch` takes. It provides more detail
than sysprof’s speedtrack plugin can provide, since it has access to
more internal GLib data.
Use it with `sysprof-cli`, for example:
```
sysprof-cli --use-trace-fd -- my-test-program
```
