Created new functions for allocating configuration data:

Browse source 
o  cfg_alloc(size) -- generic memory allocation
   o  cfg_allocu(size) -- unaligned memory allocation
   o  cfg_allocz(size) -- zeroed memory allocation
   o  cfg_strcpy(str) -- allocate a copy of a string

Also fixed a bug in lexing of string literals.
