cb51bd6b31 bufferlist: Prevent gst_buffer_list_foreach() from modifying non-writeable lists
Previously gst_buffer_list_foreach() could modify (drop or replace)
buffers in non-writable lists, which could cause all kinds of problems
if other code also has a reference to the list and assumes that it stays
the same.

a5ecb465a9 bufferlist: fix abort due to underflow when creating 0-sized list
gst_buffer_list_new_sized(0) will cause an underflow in a calculation
which then makes it try to allocate huge amounts of memory, which
may lead to aborts.

3b54dace2d tests: include config.h and don't include unix headers
In many cases the unistd.h includes weren't actually needed.

Preparation for making tests work on Windows with MSVC.

177c4ffe6a bufferlist: add gst_buffer_list_get_writable()
Ensures buffer is writable. Useful if we want to change
metadata on it such as timestamps.

5c62bce85c tests: remove some cruft from the bufferlist test
Buffers no longer carry caps, and bufferlists don't have
groups where buffers may need to be merged into one any more.

468ec5bc40 bufferlist: simplify bufferlists
We now have multiple memory blocks as part of the buffers and we can therefore
reduce the bufferlist to a simple array of buffers.

c4c06a2b88 bufferlist: Use a GQueue instead of a GList
Adding a buffer to the end of a GstBufferList is supposed to be a fast
operation, but it was not since the iterator does not advance its
nextpointer when adding buffers and GList does not have a tail pointer.
Using a GQueue to store the buffers makes it easier to add buffers to
the end of the list and this operation will now be much more efficient.

Adding an entire GList of buffers using
gst_buffer_list_iterator_add_list() will however have to iterate over
the list being added to be able to update the tail pointer in the
GQueue.

a9d1a493a7 Fixes for -Wwrite-strings
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.

2b4d127ca0 tests: fix crash and leak in bufferlists unit test
Don't access already-freed iterator, makes check-valgrind work and fixes
crash on PPC; unref buffer we're going to steal to make valgrind happy.

6438f6f9b9 bufferlist: Various cleanups
Add new method to iterate a bufferlist without having to allocate an iterator.
Add convenience method for getting an item from the list based on the group and
index.
Remove redundant _do_data callback and method.
Update unit-tests and add some more for the new methods.
