c59812e558 🔧 Fix memory leak in pthread init functions on failure 
When pthread_mutex_init() or pthread_cond_init() fails in the debug
implementation (DEBUGLEVEL >= 1), the previously allocated memory was
not freed, causing a memory leak.

This fix ensures that allocated memory is properly freed when pthread
initialization functions fail, preventing resource leaks in error
conditions.

The issue affects:
- ZSTD_pthread_mutex_init() at lib/common/threading.c:146
- ZSTD_pthread_cond_init() at lib/common/threading.c:167

This is particularly important for long-running applications or
scenarios with resource constraints where pthread initialization
might fail due to system limits.

Merge pull request #4474 from jlokier/threads-doc-fix 
Update manual about the default value of `-T#`/`--threads=#`

64c4288e92 Update manual about the default value of -T#/--threads=# 
The section about `ZSTD_NBTHREADS` already explains the default number of
threads, since it changed from 1 (commit 17beeb5).  But the option description
for `-T#`/`--threads=#` incorrectly said the default was still 1.

I noticed this when I found compression slower with `-T1` than without it.

ba59aeb674 meson: Call meson.override_dependency() if Meson is new enough 
This tells Meson that we intend libzstd_dep to be used by a parent project
if the parent looks for a dependency named "libzstd".  Without this, the
mapping from "libzstd" to our variable libzstd_dep must be encoded in the
Meson wrap file or in the parent's meson.build.

0d1f8de9ad Check for build environment instead of just _GNU_SOURCE 
Fixes the build on OpenBSD and NetBSD. It is too easy for _GNU_SOURCE
to be defined even on non-Linux systems. Found via py-zstandard with
the embedded copy of zstandard and Python defines _GNU_SOURCE.

Also simplify the Linux checking, there is no need to check the rest
of the symbol names.
