This change adds a new way for fxconv to discover metadata for file
conversions. This complements the existing mechanism of passing
parameters on the command-line.
The new mechanism activates when fxconv is called without a type
argument. Type information and metadata are searched in an
fxconv-metadata.txt file in the same folder as the resource. The
metadata file lists parameters, with some additional flexibility enabled
by the use of wildcards.
This way of declaring will replace command-line argument passing, which
currently read parameters from the unreadable and not-so-maitainable
project.cfg file. Both the GNU make and CMake build systems should use
it in the future. The current way is still supported only for older
projects and one-shot conversions outside of projects.
This makes it possible to change PREFIX at the last minute when running
install, effectively installing the files into a false packaging root
while retaining the same contents as if installed normally.
Almost-complete implementation of fxos, the disassembler in particular
is now able to detect syscalls and register addresses on the fly, plus
support for SH4-only instructions.
