Hi,
attached patch moves functions out of the huge libpayload.h into headers
according to libc/posix traditions, to simplify porting applications to
payloads.
It also adds a couple of functions:
strcasecmp, strncasecmp, strcat, strtol, strspn, strcspn, strtok_r,
strtok, perror, exit, getpagesize
baiyin cai, I added you to the recipients, as marc indicated that this
might overlap with your summer of code effort.
Comments are appreciated.

* create libc-style header files and move function prototypes there
* include those headers from libpayload.h for compatibility
* change strcmp implementation to look more like strncmp
* implement more libc functions:
strcasecmp, strncasecmp
strcat
strtol
strspn, strcspn
strtok_r, strtok
perror
exit
getpagesize
