Match functions, misc fixes, add script to check progress

[545u]

• Put functions in the list of problematic functions in configure.py in alphabetical order based on name of the TU.
• Fix small typo in scripts/readme.md.
• Separate library sources from engine sources in src/readme.md.
• Match some functions in various files.
• Added fully matched RemoveZpdZapLo by @polybiusproxy that was based on a scratch by me. However there is a TU padding problem. I think the sce/libs TU should start at address 0xF69C4 instead of 0xF69C0 like it is now. Changing the address doesn't work because the 4 NOP bytes get added right after the function.
• Added a script to locally check the project progress. Changed the checks.sh script to optionally output the progress report generated by objdiff to a new file.
• Managed to identify quite a lot of .data segment starting addresses.
• Merged split P2/UNKNOWN2 into P2/sw as it seemed to make the most sense.

The reason it adds 4 bytes of padding when you change sce/libs to start at 0xF69C4 is because all TUs are aligned to 8 bytes, i.e. the TU offsets always have to end in 0 or 8. If you don't align it to an 8-byte boundary it will add padding to make it so.

Awesome work as always! Big thanks for the progress checking script, and for sorting the list of library sources separate from the project sources. Also, good catch on the expired Discord invite.

Interesting. The last function in P2/zap cannot be taken out of the SKIP_ASM ifdef because it will overwrite the first bytes of sce/libs iirc. How should that be fixed?

It sounds like the offset of sce/libs is incorrect. Can you just push the offset of sce/libs back so the zap function doesn't overlap?

I tried that already but sce/libs gets misaligned.
