- There were a few strncpy()s that didn't terminate the string... add

safe_copy() which does strncpy the way it should be.

- switch many MAX_STRING_LENs with sizeof(foo) for the right foo, just in
case

- add const liberally to assist diagnosis

- fix two off-by-1 errors in get_tag() (it could be convinced to hammer
one byte past end of buffer)

- fix buffer overrun in get_directive()

- fix PR#1203 in a way that's fine for 1.2.x, but needs WIN32 support in
1.3

- test a few more error conditions and report them rather than doing
something lame

- buffer overrun and infinite loop in parse_string() eliminated

- removed unneeded test of palloc() and make_sub_pool() results against
NULL

- fix use of strncat which didn't \0 terminate the destination

- handle_else/handle_endif/handle_set/handle_printenv error messages
didn't include the filename
