* Kill the thread only if is alive.
* Remove rz_th_lock_guard.
* Use rz_sys_usleep since pthread_yield/sched_yield are not portable.
* Kill threads only on error.
* Avoid killing already-dead threads.
* RzThreadFunction now returns void* and added test_thread_queue.
* Removed pthread_exit
These things guarded by !__POWERPC__ work perfectly fine on Mac OS X
10.5 with PowerPC, so we can only assume they were supposed to guard
only older Mac OS X versions, but abusing __POWERPC__ for this is wrong.
Error printing for posix_spawnp has also been fixed, as it does not set
errno and instead returns an errno-like value.
* Remove `RIZIN_EXTRAS` because useless
Extras plugin should be treated as any other regular plugin, they should
not have their own directory. I believe we did not have anyway any
plugin using that directory.
* Do not use `<version>` in `/usr/share`
Users can only install one version of Rizin at a time anyway, thus
splitting the `/usr/share/rizin` directories does not really bring
multi-version install possible. At the same time, we stick to what's
common for other tools, which do not use version in `/usr/share`
* Move plugin directory to `/usr/lib64/rizin/plugins`
* Remove `RZ_HOME_BIN` env var because not useful anymore
* Introduce `rz_util/rz_path` to provide rizin paths
* Use `rz_path_system_sdb_types` whenever it makes sense
* Use some others `rz_path_*` functions instead of custom ones
* Use `rz_path` APIs for themes, fortunes and signatures
* Remove `rz_sys_prefix`
* Reduce the number of defines needed to handle home and system paths
* Reduce the number of `rz_path` functions
* Make the lib debug depending on log level and `RZ_LOG_DEBUG`
* Refactor a bit how directory of plugins are loaded
* Keep supporting old plugins directory for at least 0.4.0
* Rename `rz_str_escape_latin1()` to `rz_str_escape_8bit()`
* test_serialize_analysis.c: Change string from "latin1" to "8bit"
* `bin.str.enc`: Rename `latin1` to the more generic `8bit`
* Do not escape strings during the search
* Port `C` (metainformation) commands to the rzshell
* Improve string autodetection
* Remove `Cr` and RZ_META_TYPE_RUN
* Escape `\x1b` as `\e` character in strings
* Move string encoding options to `RzStrEncOptions` struct
* Add `esc_double_quotes` option to `RzStrEncOptions`
* Do not filter out unprintable characters for uppercase check
* Use `esc_double_quotes` when printing the string between '"' in disasm
* Use signed chars on all platforms/architectures

`portable` makes rizin use paths relative to the executable binary path,
so that all resource files (e.g. SDB files) can be retrieved without
having an hard-coded prefix in the binary. By doing so, rizin
installation directory can be moved from location to location and still
work. This is useful when having a static rizin that you want to execute
on another system.
It makes sure that all PATHs defined in rz_userconf.h are just relative
to the prefix and that, in the code, the prefix is prepended to all
these paths.
By default, pipes file descriptors are not closed on exec. This means
they are inherited by the child process. However, this may be a problem
in particular in multi-threading programs (e.g. rz-test), because EOF is
not sent to a pipe until the last pipe file descriptor is closed.
This commit makes sure that by default pipes are created with O_CLOEXEC,
so they are closed whenever an exec syscall is executed. Usually pipe
file descriptors are duplicated to be stdin/stdout/stderr of the
children process and those dupped file descriptors won't be closed on
exec.
In case pipe2 is not available (e.g. MacOS), we do a pipe + fcntl, which
is in theory racy (see man open(2)). For this reason pipe, exec, system,
etc. are wrapped in rz_sys and they use a global mutex to make sure a
pipe is either created and set as O_CLOEXEC or not created at all before
an exec operation is done.
On very old systems, O_CLOEXEC may not be available at all. In those
cases, which should be rare, we just keep a list of file descriptors
created with rz_sys_pipe that we need to close before executing another
process.
Interaction with external libs may be tricky. We expect external libs to
create files/pipes that need to be closed on exec with the right flags
and we expect rizin code to manually close pipes file descriptors as
appropriate if the exec syscall is executed by an external library
(non-rizin code).
Make sure execl is found by acr/make
