MINOR: config: extend the default max hostname length to 64 and beyond

Some users reported that the default max hostname length of 32 is too
short in some environments. This patch does two things :

  - it relies on the system's max hostname length as found in MAXHOSTNAMELEN
    if it is set. This is the most logical thing to do as the system libs
    generally present the appropriate value supported by the system. This
    value is 64 on Linux and 256 on Solaris, to give a few examples.

  - otherwise it defaults to 64

It is still possible to override this value by defining MAX_HOSTNAME_LEN at
build time. After some observation time, this patch may be backported to
1.5 if it does not cause any build issue, as it is harmless and may help
some users.

[wt: no issue reported so far and Jose rightfully asked for it in 1.5]
