This pointer is the first argument received by callbacks, and the
existing argument "data" is now automatically freed by WeeChat when the
object containing the callback is removed.
With this new pointer, the linked list of callbacks in scripts has been
removed. This will improve speed of scripts (using a lot of hooks),
reduce memory used by scripts and reduce time to unload scripts.
Following functions are affected in the C API:
* exec_on_files
* config_new
* config_new_section
* config_new_option
* hook_command
* hook_command_run
* hook_timer
* hook_fd
* hook_process
* hook_process_hashtable
* hook_connect
* hook_print
* hook_signal
* hook_hsignal
* hook_config
* hook_completion
* hook_modifier
* hook_info
* hook_info_hashtable
* hook_infolist
* hook_hdata
* hook_focus
* unhook_all_plugin
* buffer_new
* bar_item_new
* upgrade_new
* upgrade_read
The call to ruby_init_loadpath() has been moved after ruby initializations,
which fixes the crash on plugin reload.
The errors during ruby initializations are now displayed (they were hidden).
And the ruby_cleanup() is called again: it seems it does not crash any more
(tested with Ruby 2.1.5).
Now the search for Ruby is first performed with pkg-config and includes
detection of Ruby 2.0.
If not found, the old code for detection is used (for old distros or
old Ruby versions).
The specific test on Ruby 1.9.0 (to disable this version) has been
removed (1.9.0 was a dev/unstable version from 2007, quite old now).
New option script.scripts.autoload, new options autoload/noautoload/toggleautoload
for command /script, new action "A" (meta-A) on script buffer (toggle autoload).
