eval API.

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

Stefano Sabatini 4cabef0a9d 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").
