Use hierarchic names convention (prefix them with av_expr) for the

eval API.
More grep-friendly and more consistent with the rest of the FFmpeg
API.

Make strmatch() return 1 only if the string compared against the

prefix does not contain other characters which may belong to an
identifier.
This allows to distinguish for example to have different constants
with the same prefix (e.g. "foo" and "foobar").
