The version that Nico had in albumart.c of strip_extension() used to
take a length argument for the filename. Changing it to use the
existing implementation of strip_extension used everywhere else in
Rockbox meant ditching that argument - so the strcpy() in the
strip_extension() function being used now *could* cause a buffer
overflow if the destination buffer you pass in is shorter than the
filename. However, as albumart.c only calls strip_extension() once,
and the destination buffer's size is MAX_PATH + 1, I don't really see
how this could actually occur.
