Check for negative return value of read, write and lseek instead of -1
strlcpy_expand_host, sudo_getdelim, sudo_realpath: add restrict qualifier
Prefer fputs over fprintf where possible
Swap calloc arguments to use them properly.
Add check for sysconf(_SC_PAGESIZE) failure.
Use NULL, not false, in the terminating entry of test_data[].
Only really need arpa/inet.h for htons(), Solaris notwithstanding.
