Add mappings for 'MAXHOSTNAMELEN'
I couldn't find an documentation about where it should be defined
(POSIX doesn't define it), so my best guess was to find the
definitions experimentally. Combining my findings in the glibc
repo with the findings in my own Debian system, and ignoring
kernel headers and unrelated headers such as X11's, this is my
best guess.
See:
alx@asus5775:/usr/include$ grepc -k MAXHOSTNAMELEN
./X11/Xtrans/Xtranssock.c:225:#define MAXHOSTNAMELEN 255
./asm-generic/param.h:17:#define MAXHOSTNAMELEN 64 /* max length of hostname */
./protocols/timed.h:44:#define MAXHOSTNAMELEN 64
./x86_64-linux-gnu/ruby-3.0.0/rb_mjit_min_header-3.0.4.h:24134:#define MAXHOSTNAMELEN 64
./x86_64-linux-gnu/sys/param.h:54:# define MAXHOSTNAMELEN HOST_NAME_MAX
alx@asus5775:~/src/gnu/glibc$ grepc -kx '\.h$' MAXHOSTNAMELEN
./inet/protocols/timed.h:44:#define MAXHOSTNAMELEN 64
./misc/sys/param.h:54:# define MAXHOSTNAMELEN HOST_NAME_MAX
./sunrpc/rpc/types.h:102:#define MAXHOSTNAMELEN 64
