Summary:
Using `--disable-magic-debug` defines EINA_MAGIC_CHECK to always
evaluate to `1`. Eina_Binbuf's null-check relied solely on the
EINA_MAGIC_CHECK, and failed to pick up on the cases where `buf` was
passed as NULL. This has led to a segfault when a NULL `buf` was passed
in the test suite (see referenced ticket).
This fix adds an explicit NULL check.

Summary:
These three classes have essentially the same API, just different
underlying data types. This patch seeks to improve the docs for all
three while retaining or improving the consistency between them.
Several functions had completely incorrect documentation (looks like
cut-and-paste mistakes), others had missing or incorrectly named
parameter documentation, typographical errors, or other similar issues.
This also cleans up a lot of spelling and grammar errors, defines return
values as part of @return, and reformats/revises doxygen code for
consistency.
There are no changes to code, except some whitespace cleanup.

when debugging was active, this would frequently result in the monitor thread
blocking in a read() call for a fd which had already been closed by the main
thread. the main thread would be waiting for the monitor thread to fail its read()
and destroy itself, but the read() would never end without an interrupt
this reworks the monitor thread destruction to stop relying on the thread to
remove its session from the session list and instead only access the list from
the main thread, allowing sessions to always be immediately destroyed

Summary:
this changes the explicit pthread usage (and reimplementation of eina_thread_create)
to just use eina function calls. it also causes the thread to start and stop when
profiling is enabled and resolves some possible errors which could occur after
a fork or when trying to compile under windows
pthread usage: this code appears to have been 100% copied from eina_thread.c, and it
isn't clear to me why existing eina_thread api was not used. this has no functional
benefit, but it makes the code more readable
thread lifetime: there is no need to have a thread running at all times for a feature
which will be rarely used and which must be explicitly enabled by the user
windows: this file previously generated a lot of compiler warnings from unused functions
and variables since nothing here is available under windows. the entire file is now
a giant #ifndef _WIN32 to avoid any compile warnings or unexpected runtime behavior

Summary:
previously this used to mean 'the number of ms that a lock can wait for
until abort() is called once the lock is acquired' and it was useful
when trying to find contention issues with locks
unfortunately this required a bit of reading into the code to determine,
and it made the common case of setting values to 1 fail in some cases,
as this is a very short amount of time. also the documentation explicitly
gives '1' as an example setting for this variable, which will cause immediate
abort() in most cases when debugging was enabled since things are much slower
this variable now is the number of usec that a lock can wait for before abort()
is called, and the lowest value that will be checked for abort()ing is 100, meaning
that '1' is valid again

This reverts commit 0d91088d0f.
It also includes a workaround for OSX where RT signals aren't
supported due to kernel age (too old a fork of freebsd). fixes D6310
and T7029
This include is necessary according to POSIX. Without it, build
fails on certain platforms (QNX). It may already be included
implicitly in some of those files, but declare intent.
Fixes T6667.
Summary:
if profiling is not enabled then reaching this signal handler will always
result in a crash
moreover, the signal handler has no functional value if profiling is not active,
so do not add it until that point
