garray: refactor and optimize ga_concat

Browse Source 
I've checked all uses of ga_concat in the codebase:

- ex_cmds2.c
- ex_getln.c
- eval.c
- message.c
- regexp-nfa.c
- term.c
- spell.c

None of them concats the garray with itself. This makes it safe to use the
faster memcpy() instead of memmove(). This change was also documented.
