By default, gst_parse_launch_full() creates a GstPipeline if there's more
than one toplevel element. Add a flag to let it use a GstBin instead.
Also fix the parser to let it use this flag for GST_TYPE_ELEMENT property
values, to avoid having GstPipelines inside other GstPipelines.

gst_parse_launchv, gst_parse_launchv_full and gst_parse_launch_full
all return floating refs, the same as gst_parse_launch, which just
calls gst_parse_launch_full internally anyway.
Add a unit test assertion to check it's true.

This reverts commit dd9fedb41f.
This is not the right place to escape the \, we should only escape the spaces to
keep the arguments together that were provided as one group (with quotes on the
shell).
If we have a file called Foo\Bar.ogg, there is no way to pass
that filename properly to filesrc in gst_parse_launch(), since
gst_parse_unescape() will just unescape \x to x.
Not cherry-picking this into 0.10 since there are apparently
apps that work around this problem and which would break if
we fixed it there too.

Don't export those 35-something random _gst_parse_yy* symbols. These were
never in any header files and also blacklisted from our .def files, in
case anyone wonders.

Maintain API and ABI when --disable-parse is used. Now that
we have an appropriate error code, we can just return NULL and the
appropriate error when gst_parse_launch() is used despite it having
been disabled (#342564).
* tests/check/Makefile.am:

* tests/check/pipelines/parse-disabled.c:
Make sure these functions exist and return NULL plus a GError when
--disable-parse is used.

Make the parser reentrant and recursively callable. This requires flex
>= 2.5.31, for older versions pregenerated sources are used as we
can't bump the build dependency. Finally fixes#349180.
* gst/gstparse.c: (gst_parse_launch):
Drop the HAVE_MT_SAVE_FLEX #ifdefs as we always use a new enough flex
now anyway.

If the installed flex version is too old use pre-generated parser
sources. These pre-generated parser sources are always updated when
the actual flex/bison sources change but require everybody who wants
to change something in the parser to have flex >= 2.5.31 installed.

Original commit message from CVS:
GST_DEBUG reorganization
This is a big diff (ca 450k), containing loads of stuff:
- gstinfo.[ch] complete rewrite
- changing of all GST_DEBUG messages to reflect that change
- reorganization of subsystem disabling
- addition of gstconfig.h.in so we can track the disablings
- <gst/gst.h> does not include <unistd.h> and <config.h> anymore
- documentation updated for gstinfo stuff (build the docs yourself to know what changed)
- bugfixes for making of the docs (files from CVS are not deleted anymore
- testsuite for debugging changes in testsuite/debug
expect breakage
Original commit message from CVS:
rewritten pipeline parsing lands. Have fun breaking it.
regressions:
- No support for filtered links. If anybody needs this, please contact me and I'll add it as fast as possible.
improvements:
- The pipeline building actually works as expected.
- syntax compatible nearly everywhere but more flexible
- better property parsing (you can now set enums by name or nick)
- uses locked_state to allow for delayed pads
- can connect video pipelines without the need for queues
- allows properties on bins
- does not return a bin, but an element.
You may want to read docs/random/company/gstparse to learn how it works.
Original commit message from CVS:
- implement FLOATING flag on caps/props
- use gstmemchunk for caps/props
- implement remove_entry for props
- various refcounting functions
- fix refcounting on caps/props
- use tracing for caps/props/propsentries
- fix memleak in transform functions
- fix refcounting on elementfactory padtemplates
- add dispose for padtemplates
- shortcut pad negotiation early on
