* platform_win32: Fix sizeof for DEFAULT_DIR_PLAYLIST.
* frontend/drivers/platform_win32.c (frontend_win32_env_get): Check
the size of correct destination array.
* frontend: Honor the LIBRETRO_ASSETS_DIRECTORY environment variable.
This builds on 763fcd8267 ("unix, win32: Allow set the default
libretro_directory via environment variable") to also allow specifying
the assets directory via an environment variable.
* frontend/drivers/platform_unix.c (frontend_unix_get_env)
<libretro_assets_directory> New variable. Use it to set
DEFAULT_DIR_ASSETS, when available.
* frontend/drivers/platform_win32.c (frontend_win32_env_get): Likewise.
* platform: Honor the LIBRETRO_DIRECTORY environment variable.
Until now, and unlike the defaut core directory, the default
core *info* directory would be hard-coded relative to the installation
directory. Honor the LIBRETRO_DIRECTORY environment variable the same
instead.
* frontend/drivers/platform_unix.c (frontend_unix_get_env): Set
DEFAULT_DIR_CORE_INFO default to the value of the LIBRETRO_DIRECTORY
environment variable, if available.
* frontend/drivers/platform_win32.c (frontend_win32_env_get): Likewise.
* platform: Honor the LIBRETRO_AUTOCONFIG_DIRECTORY environment variable.
* frontend/drivers/platform_unix.c
(libretro_autoconfig_directory): New variable.
(frontend_unix_get_env): Set DEFAULT_DIR_AUTOCONFIG to the value of
the LIBRETRO_AUTOCONFIG_DIRECTORY environment variable, if available.
* frontend/drivers/platform_win32.c: Likewise.
* platform: Honor the LIBRETRO_VIDEO_FILTER_DIRECTORY environment variable.
* frontend/drivers/platform_unix.c
(libretro_video_filter_directory): New variable.
(frontend_unix_get_env): Set DEFAULT_DIR_VIDEO_FILTER to the value of
the LIBRETRO_VIDEO_FILTER_DIRECTORY environment variable, if available.
* frontend/drivers/platform_win32.c: Likewise.
* platform: Honor the LIBRETRO_VIDEO_SHADER_DIRECTORY environment variable.
* frontend/drivers/platform_unix.c
(libretro_video_shader_directory): New variable.
(frontend_unix_get_env): Set DEFAULT_DIR_SHADER to the value of
the LIBRETRO_VIDEO_SHADER_DIRECTORY environment variable, if available.
* frontend/drivers/platform_win32.c: Likewise.
* platform: Honor the LIBRETRO_SYSTEM_DIRECTORY environment variable.
* frontend/drivers/platform_unix.c
(libretro_system_directory): New variable.
(frontend_unix_get_env): Set DEFAULT_DIR_SYSTEM to the value of
the LIBRETRO_SYSTEM_DIRECTORY environment variable, if available.
* frontend/drivers/platform_win32.c: Likewise.
* configuration: Have environment variables override configuration.
Because the configuration file is systematically written when
RetroArch terminates, persisting any previous default/configured
value, setting the LIBRETRO_DIRECTORY, LIBRETRO_ASSETS_DIRECTORY, etc.
environment variables would not have an effect unless the
retroarch.cfg configuration file was cleared.
This seems to go against the common expectation that environment
variables are set by users to *override* the default behavior or
configuration of an application.
* configuration.c (config_load_file) <libretro_directory>
<libretro_assets_directory, libretro_autoconfig_directory>
<libretro_system_directory, libretro_video_filter_directory>
<libretro_video_shader_directory>: New variables. Use the values of
the LIBRETRO_DIRECTORY, LIBRETRO_ASSETS_DIRECTORY,
LIBRETRO_AUTOCONFIG_DIRECTORY, LIBRETRO_SYSTEM_DIRECTORY,
LIBRETRO_VIDEO_FILTER_DIRECTORY and LIBRETRO_VIDEO_SHADER_DIRECTORY
environment variables instead of their corresponding configured
values, when set.
* docs/retroarch.6: Document the environment variables honored and
their behavior.
* add achievement data to netplay save state
* honor achievement state from netplay server
* keep processing achievements if menu doesn't pause game
* remove unused variable
* only CRC coremem
* force send savestate on join and hardcore change
* allow hardcore enablement to be synced to clients
* still calculate cheevos_size for non-server
* use appropriate buffer
* optimizations for when achievements are disabled
* support interfacing with older protocols
* formatting
* c89
* Use given latency
* Fix (non)blocking microphone
* Mute microphone on startuo
* Reset buffer when the microphone stops
* Delete client-info handler
* Refactor the naming conventions, styling
* playlist_get_old_format_metadata_value - now returns size_t
* fix bug where string copy was being made with strdup before
anything got written to the string
