use-mmap functionality has been removed in 0.11 and doesn't really
have any performance advantages in most cases anyway. Deprecate
"sequential" property to hint sequential access in mmap mode and
make it non-functional. Chances are no one was using this ever
anyway, or inappropriately.
Remove madvise() calls. We would need to do extensive configure
checks to handle these properly on different systems, and it
doesn't seem worth adding that for code that's already removed
in 0.11 or questionable anyway (like madvise DONTNEED right
before munmap).

_create() is a pad function set by ourselves, therefore we're sure basesrc
is a GstFileSrc.
Speeds up _create() by 17% and the total call by 8% (instruction calls measurements
done with valgrind).
Fixes#610246

Add "sequential" property, off by default, to use madvise and hint
to the kernel that sequential access is desired.
Touch all retrieved pages by default to ensure they are pulled
into memory. (Closes#345720)

Add a use-mmap property to enable easier testing of all code paths.
Bump rank to PRIMARY, so filesrc is the preferred file reader and used
in the absence of gnomevfssrc. (Closes#340501)
Original commit message from CVS:
Various fixes for unseekable, unmmapable, and non-normal files, so that
fallback to read() rather than mmap() works.
Allow newsegment events with start == end, so that cases where that's
correct work (e.g. filesrc on a zero-size file).

Original commit message from CVS:
implement URI schemes
Elements can now register as a source or sink for a protocol and applications can use gst_element_make_from_uri () to get an element that handles a given URI.
This patch provides:
- removal of old broken URI handling scheme.
- new URI handling using interfaces.
- updates for registry to save handled URIs.
- interface for URI handlers.
- implementation of that in filesrc and filesink for the file:// URI
- extension to pipeline parsing to allow specifying only a URI instead of element
Does not include:
- tests
- inclusion in docs build
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:
* minor typographical change to autogen
* added --with-html-dir option to configure
* more robust docbook checks
* convert to standard docbook makefiles, at least for the gst/ directory
* added filesrc.h so that docbook can know about filesrc
* updated -sections.txt because docbook is incredibly stupid and requires that at
least one of the lines between <section> and </section> is not an entity
* first pass at possible getting the docs to build on glib2, untested
