This feature turns intra library calls into direct function calls and thus makes
them a little faster. The downside is that this causes problems for e.g.
LD_PRELOAD based tools. Thus add a configure option to turn it off.
Adds 2 variants for the gst_date_time_from_unix_epoch function,
one for UTC and another for local time.
API: gst_date_time_new_from_unix_epoch_utc
API: gst_date_time_new_from_unix_epoch_local_time

Only try to build (pseudo-)C++ unit test if a working C++ compiler has been
found, otherwise the build will fail. (We do this to make sure our headers
are 'C++ clean').
Sets up a GST_PKG_CONFIG_PATH variable for use in Makefile.am
(avoids trailing ':' in PKG_CONFIG_PATH used). A useful side
effect of this is also that the PKG_CONFIG_PATH environment
is now logged in the configure output.
This first checks what is required for ISO C99 support and sets the relevant
compiler parameters and if no C99 compiler is found, it checks for a
C89 compiler. This enables us to check for and use C89/C99 functions
that gcc hides from us without the correct compiler parameters.
Apparently gcc warns that GstMiniObject is not castable to
GstEvent/Message/Buffer due to them containing 64bit variables, even
though ARM hackers claim that those only need 4byte alignment. And as
long as gcc behaves that way, this warning is not very useful.
So we'll remove the warning until this problem is fixed.

Check for ability to divide uint128_t values, since that what
we actually use it for (in gstutils.c). The existence of a
uint128_t type doesn't mean the compiler can actually generate
code for it. Also make sure that we can actually link the
result successfully.
Fixes bug #614767.
This is how we do it in the other modules, and gets rid of the annoying
dirty status for common when doing git status (at least once you clean
out the old files from there).
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
It triggers for a lot of GStreamer API (even though those triggers are
wrong most of the time).
I missed it because it only triggers with -O2, and I was using -O0.
None of these flags cause warnings anymore, so no fixes necessary.
The flags are:
-Wformat-nonliteral
-Wformat-security
-Wold-style-definition
-Wcast-align
-Winline
-Winit-self
-Wmissing-include-dirs
-Waddress
-Waggregate-return
-Wno-multichar
-Wnested-externs
The alignment guaranteed by malloc is not always sufficient. E.g. vector
instructions or hardware subsystems want specifically aligned buffers. The
attached patch will use posix_memalign if available to allocate buffers.
The desired alignment can be set when running configure using the new
--with-buffer-alignment option.
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.

Adds that warning to configure.ac
Includes a tiny change of the GST_BOILERPLATE_FULL() macro:
The get_type() function is no longer declared before being defined.
