Summary: serious bug: unQuoteBytea allocates buffer that is too small

Initial Comment:
In the case where unQuoteBytea is called with a string
that has no escaped characters, and unQuoteBytea
behaves like strcpy() to simply copy all the bytes in
the original string unmodified to the destination
string, the buffer is too small by one char. The buffer
allocated has the size strlen(sin) when it should have
the size strlen(sin)+1 to account for the terminating
NUL byte in C strings.

I have attached a patch to correct this problem. It
caused me a lot of pain with strange, semi-random
seeming bugs in my program. :-)
