Attempt to add back support for builddir != srcdir. Use absolute paths
instead of relative paths based on pcfiledir this time to make things
clearer - there's not really any need for uninstalled trees to be
relocatable without re-running configure.
I don't know how this ever worked, as it seems to put -I./..
and -I./../libs verbatim into the includes, at least with
current autotools versions.
This reverts commit 279a80ff27.
As the headers were broken in 0.10.26 the functions weren't really
usable back then, so we should advertise them as being there only
since 0.10.27.
Spotted by Mart Raudsepp.
When doing pad_allocs, use non-fixed caps suggestions and
try to fixate them before using. This makes possible to
have suggested buffer size with 0 in basetransform just
to signal upstream a renegotiation is needed

prctl is supposed to take 5 arguments. It used to work with 2 arguments on some
versions of libc because it is defined as a varags function there.
See #611911
This either must never happen (which makes sense in this case) and thus should
use assert() or we should use a traditional if (poll_data->message) return;
to avoid differnet behaviour of intenal api when compiling with
G_DISABLE_CHECKS.
This avoids creating empty caps and destroying them in the case of an error. We
also avoid double checking in other code path where we call the internal api.
See 8fe63000de for why having a TRUE/FALSE
return value is a bad idea.
I've scanned a few plugins and they generally get it wrong and aren't
unloadable when they return FALSE.
This is what can happen in a plugin_init function:
- An element based on GstBaseSink is registered
- Other elements fail to register
- The plugin_init function returns FALSE
Now if this the plugin is the first plugin to link against
libgstbase.so, it will have caused libgstbase.so to be loaded and static
strings from that library will have been added to gobject while
registering GstBaseSink.
So unloading the plugin will cause those strings to go stale and the
next plugin using GstBaseSink will crash. So we must not unload modules
after calling into them ever.

Newer versions of BASH (4.x?) seem to dislike using -1 for a return. Even
though it's documented as being signed, BASH complains about it, so use
255 instead.
This brings total call speedups between 5% and 25%.
gst_caps_set_simple_valist: +5%
gst_structure_set_valist: + 10%
gst_structure_id_set_valist: +25%
gst_tag_list_add_valist: +5%
Measured using valgrind when run over the discovery of 200 media files.
Fixes#610256
