Add an index to gst_buffer_take_memory() so that we can also insert memory at a
certain offset. This is mostly interesting to prepend a header memory block to
the buffer.
This changes some APIs in compatible ways:
- Some functions now take "const char *" arguments, not "char *"
- Some structs now have "conts char *" members, not "char *"
The changes may cause warnings when compiling with the right warning
flags. You've been warned.
Also adds -Wwrite-strings as a warning flag in configure.ac.

Original commit message from CVS:
* tests/check/libs/controller.c:
* tests/check/libs/typefindhelper.c:
* tests/check/pipelines/parse-launch.c:
Don't use GST_PLUGIN_DEFINE_STATIC, it is not portable and is
going to be deprecated (see #498924).
Original commit message from CVS:
* libs/gst/base/gsttypefindhelper.c: (buf_helper_find_peek):
Fix off-by-one bug that would only allow peeks of N-1 bytes
from the start even if the buffer to typefind on contains
in fact N bytes of data (makes vorbis typefinding from a
vorbis identification header buffer work).
* tests/check/Makefile.am:
* tests/check/libs/.cvsignore:
* tests/check/libs/typefindhelper.c: (GST_START_TEST),
(gst_typefindhelper_suite), (main), (foobar_typefind),
(plugin_init):
Add very basic unit test for gst_type_find_helper_for_buffer()
that checks for the problem fixed above.
