Late g_thread_init() is fine with newer GLib versions and done automatically
from g_type_init() there, so don't warn if the application hasn't called
g_thread_init() yet when gst_init() is called with new GLib versions.
Fixes#608398.
We require threads to be supported in any case and defining this
will simplify the mutex, condition variable, etc. macros from gthread
to not always check if threads are really supported.
Fixes bug #607481.
The OGI links are dead, so remove them. Also remove the paragraph that pointed
to OGI and DS. Only mentioning DS there made it a but pointless. Add a generic
paragraph instead that tells a bit about the usecases gstreamer covers.
Possibly fixes GObject class creation/unref race conditions when
creating the last-message string in fakesink for events with
structures that have fields with these enum types.
Fixes build with -Werror caused by '_FILE_OFFSET_BITS redefined' warning on
OpenSolaris where _FILE_OFFSET_BITS may be defined both in our config.h
and via stdio.h (#575695).
This will be mostly useful in all elements that have some kind of internal
seek/index table. Currently almost all of them (or even all of them)
are using a linear search although the used array is already sorted,
wasting some CPU time without good reason.
Fixes bug #573623.

Remove GST_DISABLE_(ENUMTYPES|INDEX|URI) everywhere.
Disabling the indexers and URI handler code will only reduce the
required amount of memory by a very small amount but on the other hand
requires much more maintaince work. Apart from that many places of
code are broken when disabling them.
Disabling the enum types doesn't reduce the required amount of memory
by more than a few bytes and makes it hard to fix bugs like #539772,
i.e. use the enums as GObject properties.

interposing to marry them all, which doesn't work on Solaris.

API: add gst_plugin_register_static() and deprecate

(#498924).
Also, in _gst_plugin_register_static(), make sure to call
g_thread_init() before calling GLib functions such as
g_list_append() if we're not initialised yet, since that
may lead to random crashes with older GSlice/GLib versions.

Original commit message from CVS:
* gst/gst.c: (_gst_disable_segtrap):

we can use gst_segtrap_is_enabled() there now that we have that API.

to do the getenv here (and export the variable).
* gst/gstdebugutils.c: (debug_dump_element),

* gst/gstplugin.c: (_gst_plugin_fault_handler_setup),

Original commit message from CVS:
* gst/gst.c:
Don't use GST_INFO before the debug system is actually initialised
(shouldn't do any harm, but won't print anything either, so we can
just as well remove it).
* gst/gstinfo.h:
GST_CAT_LEVEL_LOG_valist(), which is our inline helper function for
compilers that don't support variadic macros (such as MSVC), should
check for debug_level <= __gst_debug_min as well, since that's the
function called from all the level-specific GST_CAT_*_LOG_OBJECT()
inline helper functions. Should improve performance a bit, but also
makes sure uses of GST_INFO et.al are ignored if the debugging
system isn't initialised yet (instead of printing an assertion
failure).
Original commit message from CVS:
* gst/gst.c:
Add GST_DISABLE_OPTION_PARSING, in order to disable option
parsing for embedded systems.
* gst/gstelementfactory.c:
Allow gst_element_register() to be called with plugin==NULL.
Did nobody notice that static elements were broken?
Original commit message from CVS:
* gst/gst.c: (gst_init_get_option_group):
Make warning about late g_thread_init() calls a bit more explicit,
so that it's more obvious to application developers what they need
to do if a user files a bug against their application.
Original commit message from CVS:
* gst/gst.c: (gst_init_get_option_group), (gst_init_check),
(init_pre):
Call g_thread_init() first thing in gst_init() / gst_check_init().
When initialisation is done via gst_init_get_option_group() and
GOption parsing, issue a warning if the GLib thread system has not
been initialised yet by the time gst_init_get_option_group() is
called, as it's quite likely other GLib functions such as
g_option_context_new() have been called already then, and
g_thread_init() must be called before any other GLib function. The
application in question must be fixed in that case, since memory
corruption might happen otherwise.
We issue the warning because even if the GLib folks decide to work
around the problem on their end in future, this is still an issue
with all GLib versions >= 2.10.0, so we should warn until we depend
on a GLib version we know to be safe.
Update documentation as well.
Closes bug #391278.

Original commit message from CVS:
* gst/gst.c: (init_pre), (init_post):
init_pre() and init_post() might be called via our GOptionGroup or

If the fork()'ed child process can't write the updated registry cache

when creating elements because seemingly no plugins are available).

also separate fork() and non-fork() code paths. Fixes#344748.
