0d57bd3198 taglist: Avoid combinatorial explosion when merging tags
When appending/prepending tags, avoid re-creating (and copying) lists if we already
have one and instead just append/prepend the GValue to the list.

bd48ba333d structure: Add gst_structure_new_from_string()
Convenience API for bindings, gst_structure_from_string() returns
a tuple (structure, end_ptr) in bindings and is unintuitive to use
because of that.

7fc2602761 gst: Don't intercept --help in gst_init()
Before this patch gst_init would intercept --help, causing for example
cheese's --help to look like this:

[hans@shalem cheese]$ cheese --help
Usage:
  cheese [OPTION...] - GStreamer initialization

Help Options:
  -h, --help                        Show help options
  --help-all                        Show all help options
  --help-gst                        Show GStreamer Options

gst_init is the only gfoo_init function which does this.

2e1db58e11 gstvalue: Add _append_and_take_value() public variants
API: gst_value_array_append_and_take_value
API: gst_value_list_append_and_take_value

We were already using this internally, this makes it public for code
which frequently appends values which are expensive to copy (like
structures, arrays, caps, ...).

Avoids copies of the values for users. The passed GValue will also
be 0-memset'ed for re-use.

New users can replace this kind of code:
gst_value_*_append_value(mycontainer, &myvalue);
g_value_unset(&myvalue);

by:

gst_value_*_append_and_take_value(mycontainer, &myvalue);

73895c05b1 pad: Store sticky events even if the pad is flushing
But do this only for events that are not dropped by flushing,
i.e. do it only for everything except SEGMENT and EOS.

Without this we might drop a CAPS event if flushing happens
at an unfortunate time and nobody is resending the CAPS event.

e8a9f7acdf printf: fix handling of old printf extension specifiers for ABI compatibility
Fixes abort when the old specifiers are used. Fix up the conversion
specifier, it would get overwritten with 'c' below to the extension
format char, which then later is unhandled, leading to the abort.
Also fix up and enable unit test for this.

Source elements with limited bandwidth capabilities and supporting
buffering for downstream elements should set this flag when answering
a scheduling query. This is useful for the on-disk buffering scenario

hardcoded protocols.

18a7a1d062 gst: Add better support for static plugins
API: GST_PLUGIN_STATIC_DECLARE()
API: GST_PLUGIN_STATIC_REGISTER()

Based on a patch by Håvard Graff <havard.graff@tandberg.com>.

This now allows GST_PLUGIN_DEFINE() to create a static plugin if
GST_PLUGIN_BUILD_STATIC is defined. The resulting plugin can be
statically linked or dynamically linked during compilation but
can't be dynamically loaded during runtime.

Also adds GST_PLUGIN_STATIC_DECLARE() and GST_PLUGIN_STATIC_REGISTER(),
which allows to register a static linked plugin easily.
It is still required to manually register every single statically linked
plugin from inside the application as this can't be automated in a portable
way.

A new configure parameter --enable-static-plugins was added that allows
to build all plugins we build here as static plugins.

Fixes bug #667305.

91c42b9380 printf: use sprintf() to work around glibc complaining about %n in a writable format string
Don't use snprintf(), but use sprintf instead and do our own
length calculations, because glibc may complain about us passing
%n in a format string if the string is in writable memory, and
here the format string is always in writable memory since we
construct it on the fly. This happens if glibc has been compiled
with _FORTIFY_SOURCE=2, which seems to be the case on some
distros/systems). On the upside, we now use the sprintf code path
on all systems which should be better from a maintenance point
of view.

f43b756f39 plugin: fix name expansion for GST_PLUGIN_DEFINE macro
Make GST_PLUGIN_DEFINE use G_STRINGIFY() to convert the name argument
into a meaningful string. The advantage of this is that `name' can be
expanded from other macros defined in the plug-in element.
