Fix a few strncpy bullshit

Turns out the codebase is filled with calls to strncpy on non null-terminated strings, which causes !885 (merged) to not work properly in some cases.

I tried fixing that but fixing all such strings is a lot of work, so I defaulted to reverting the old entry searching functions, and instead adding an alternate version that can find long names, which is used by Lua only for now.

Ideally the long-term goal would be to eventually completely get rid of the old functions, and use only the long name ones.

Compare with previous version

Turns out that second commit caused weird slowdowns at level load, so I reverted it. It did not contain important changes anyway.
