patch 8.2.3620: memory leak reported in libtlib
Commit: https://github.com/vim/vim/commit/b3a29558eedac9979f5276ae914934b7b7cbe06b

patch 8.2.3620: memory leak reported in libtlib
Problem: Memory leak reported in libtlib.
Solution: Call del_curterm() when cleaning up memory. Rename term.h to
termdefs.h to avoid a name clash.
