Before this patch the function was using RZ_PREFIX even when IS_PORTABLE
was set, making the function not working well because RZ_PREFIX might
not exist in the system where the portable build is used (the path was
passed to realpath(), which requires an existing path).
This patch fixes the problem by searching for the BINDIR without using
realpath() on the RZ_PREFIX. Moreover, it avoid retrieving the same
prefix every time by saving it in a global variable.
* Add rz_constructor.h to allow defining constructors/destructors on
multiple compilers.
* Create `rz_windows.h`
* Move `RzThread` structure definitions to internal header
* Create and use `rz_th_get_user()` API to avoid exposing `RzThread` layout in external header
* Make `rz_th_self()` an IPI
* Use `_wmkdir()` in `rz_sys_mkdir()` on Windows
* Remove unused `winkd_break_read` function
* Remove `RzIORap` definition from `rz_io.h`
* Remove include of `Windows.h` from `rz_types.h`
* Use `rz_windows.h` when necessary
* Remove `RzCoreRtrHost` definition from `rz_core.h`
* Remove `rz_socket.h` include from `rz_core.h`
* Add an option to provide a custom prefix for portable binaries
* Use bindir's depth to find the portable root path in rz_path_prefix
* Skip the prefix folder check if we are not in bindir
* 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
