This commit adds convenience auto naming in the following cases:
* When building from a non wildcard-named template, the name of the template is
automatically assigned to the Pad. User can override with a specific name by
calling `name()` on the `PadBuilder`.
* When building with a target and no name was provided via the above, the
GhostPad is named after the target.

Previously, with add_watch()/add_watch_local() you had to remember
calling remove_watch() in order not to leak the bus, the watch source
and two associated file descriptors. Now these methods instead return an
object of type BusWatchGuard that will automatically remove the bus
watch when the object is dropped.

Currently only covers what is needed to keep code compiling, plus
everything caps/structure/tags related.
This avoids unnecessary heap allocations for adding the NUL-terminator
of C strings, and especially makes caps/structure handling as efficient
as in C.

As a side-effect, this also now includes the element factory name in the
error messages instead of giving the same error string for every
factory.

Also let them all go through the same, single object construction code.
... users would be able to bypass the range checks and build a
defined Rust value which would be interpreted as `None` in C code.
Added format module examples for formatted values constructions.
Some operations were implemented on types that wouldn't result in
the expected physical unit. E.g.:
- `ClockTime / ClockTime` results in a unit-less factor.
- `u64 / ClockTime` would result in a `1 / ClockTime`. Since we don't
use any `Frequency` type, this operation is removed. Users should
use the `ClockTime` accessors to compute the expected value.
This commit also adds:
- multiplications with integers as the left hand side operands.
- `Partial{Eq,Ord} for `Signed<T>` with `T` as left hand side operand.
- `opt_add` / `opt_sub` for `Signed<T>` with `T` as left or right hand
side operands.
- missing tests for `Partial{Eq,Ord}` and `OptionOrd`.
This implementation can interfere with unrelated code and was removed:
- `Signed<usize>.` `PartialOrd` makes existing code computing the len
of slices needing type annotation because the len is later used in
a comparison for which the compiler is unable to determine if
the len is `Signed<usize>` or `usize`.
This is required for OpenGL to work nowadays on macOS. Simply running an
CFRunLoop on the main thread is not sufficient.
Thanks to Philippe Normand for testing this on macOS and making sure it
actually compiles and works.
When importing the prelude of a crate like `gst` the `glib` prelude is
provided too. Shedding these imports saves quite a few lines and
adheres to keeping it simple; we're not reexporting base/parent preludes
for no reason :)
