6eb6d9ec38 docs: remove outdated and pointless 'Last reviewed' lines from docs
They are very confusing for people, and more often than not
also just not very accurate. Seeing 'last reviewed: 2005' in
your docs is not very confidence-inspiring. Let's just remove
those comments.

8b51e9dc60 gstvalue: Prevent division or modulo by zero
The step can end up being zero if the underlying value isn't a valid
range GValue.

In those cases, return FALSE.

We don't use g_return*_if_fail since it will already have been triggered
by the above-mentionned _get_step() functions.

3ea6b04c10 gstvalue: Fix comparision of double range
Checking twice the lower bound is great (you never know, it might change
between the two calls by someone using emacs butterfly-mode), but it's a bit
more useful to check the higher bound are also identical.

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);

7477b25df5 caps: Add new data type for handling caps features to the caps
These are meant to specify features in caps that are required
for a specific structure, for example a specific memory type

Semantically they could be though of as an extension of the media
type name of the structures and are handled exactly like that.

507fc9cea7 value: avoid duplicates when intersecting lists
Fixes negotiation taking a ridiculous amount of
time (multiple 10s of seconds on a core2) when
there are duplicate entries in lists.

Could have a negative performance impact on other
scenarios because we now have to iterate the
dest list to avoid duplicates, but we don't
have a lot of lists any more these days, and
they tend to be small anyway. The negatives
are hopefully countered by the positive effects
of reducing the list length early on in the
process. And in any case, it's the right thing
to do.

Based on patch by Andre Moreira Magalhaes.

ffdefd7720 value: add GstTagList serialisation/deserialisation
So we can serialise/deserialise taglists inside structures,
which used to work automagically before because GstTagList
was just a typedef to GstStructure (same for the GType),
but now that it's a separate GType we need to register
explicit functions for this.

Helps with GDP stuff in pipelines/streamheader tests.

5a6be2201d datetime: fix compare function
Take into account that not all fields might be valid (though they
are valid in the GDateTime structure). But we should just return
unordered if the set fields don't match. Also, don't check
microseconds when comparing datetimes, since we don't serialise
those by default if they're available. This ensures date times are
still regarded as equal after serialising+deserialising.

3e8d6d6064 value: remove gst_value_register_{subtract,union,intersect}_func() API
There isn't really any need to provide public API for that. It's not
used anywhere in practice, and we aim to provide an API that works
for GstCaps, not some kind of generic set manipulation API based on
GValue. Making this private also makes it easier to optimise this
later. We can always put it back if someone actually needs it.

we'd just use GDateTime for everything, but it

2012-01 for example).

ab0763f0e8 value: Fixed serialization for short fourccs.
"Y16 " and "Y8  " were not displayed properly because the space
character is not alnum.  A unit test is also included.

Fixes bug #621282.

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.

ec10b764b9 caps: Fail when fractions are followed by random text
Previous code treated "1/1yourmom" the same as "1/1" and "1wimsmom" the
same as "1". Now the code is stricter and will fail to convert a
fraction when followed by garbage text.

4743e62be8 caps: Allow 1/max as the minimal fraction value > 0
This is useful for formats that require a valid framerate (like
theoraenc).

a5626f239a gstvalue: Use fast gst_value_list_{size|get_value} macro accessors
gst_value_list_size and gst_value_list_get_value will do a series of
extra checks due to being public methods.
When we use them from within gstvalue.c we can directly use them without
the extra checks.

0ed24bc50e utils: API: Add multiplication and addition functions for fractions
gst_util_fraction_add()
gst_util_fraction_multiply()

These work on plain integers instead of GValues to
keep the overhead as low as possible.

e4257e8d5f gstutils: API: Add fraction helper functions
gst_util_greatest_common_divisor()
gst_util_double_to_fraction()
gst_util_fraction_to_double()

Using these instead of going over GValue has much lower overhead.

Also add float<->fraction transform functions for GValue.
