When allocating the h_table array use the size of struct hash_head,
not the size of a pointer. From Joris Vink. OK fcambus@

Replace <sys/param.h> with <limits.h> and other less dirty headers where
possible. Annotate <sys/param.h> lines with their current reasons. Switch
to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_N

Replace <sys/param.h> with <limits.h> and other less dirty headers where
possible. Annotate <sys/param.h> lines with their current reasons. Switch
to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change
MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where
sensible to avoid pulling in the pollution. These are the files confirmed
through binary verification.

add a hash table mechanism based upon hcreate(3) but one that allows
us to maintain multiple hash tables concurrently.

add a hash table mechanism based upon hcreate(3) but one that allows
us to maintain multiple hash tables concurrently.

immediatly start using it to keep track of what directories
we have already created and what CVS dirs we already created so
we do not recreate them when we do not need to.

we will be switching more internals to use this soon.
rejoice for cheaper lookups.
