c7124b5: Fix opus craches with large embedded album art
Use the tlsf malloc and friends instead of the silly codec_malloc to get actually working free and saner realloc that doesn't leak memory. Makes files with moderately sized embedded AA play on targets with large enough codec buffers and files with too large AA are now skipped rather than crashing. Fixes crash when playing example file in FS #12842.
4877f61: Rework rbspeex dependency generation to use single dependency files.
Similar as done in d2b8f91 change dependency generation to use one file per source file. This removes the need to have external tools installed on Windows. Previously Cygwin or msys tools needed to be in the system PATH which was problematic at times.
This means that now building on Windows (using MinGW) doesn't require additional tools anymore.
e073bc9: Implement dependency generation in libtools.make.
Automatically generate dependency files for all sources so changes in headers are picked up automatically. Use one dependency file for each source file, since that allows to create them without using external tools (except the compiler of course).
