Use the more specific already included exception classes for common
errors to keep things more understandable.

sws_getCachedContext will set a default sampling method if 0 is passed
to the flags argument. This means that when it is called again, the
flags argument will not match the flags in the context, so a new one
will be allocated every time.
To get around this problem, we assign an explicit sampling method, one
that also happens to be more efficient and just as good for this
use-case as the default one, which is bicubic interpolation.

The scaler is now informed of the colour space encoded into the stream
so that it may do the proper conversion.

This ensures that the buffer is allocated with the correct alignment and
padding for use with sws_scale.
This fixes out-of-bounds writes which would in some cases cause
segmentation faults and/or heap corruption.

It's more readable than 0, and a bit safer than NULL, so let's try to
follow modern norms.

Avoid having our own custom stuff and instead use the modern, standard
types, for familiarity.

Everything in flags is already handled at a higher level.
