PKG_REFCOUNT_DBDIR in the environment when running the +* scripts.
PKG_METADATA_DIR is the location of the +* files after the package is
registered. PKG_REFCOUNT_DBDIR is the location of the reference counts
database directory. If PKG_REFCOUNT_DBDIR is left unset, then it
defaults the the location of the package database directory with
".refcount" appended to the path, e.g. /var/db/pkg.refcount.
pkgviews users should explicitly set PKG_REFCOUNT_DBDIR in the shell
environment to ensure that all packages will use the same refcount
database.
These changes allow the +INSTALL and +DEINSTALL script to keep state
in +* files within ${PKG_METADATA_DIR}, and to store reference counts
in ${PKG_REFCOUNT_DBDIR} to handle usage of resources outside of
${LOCALBASE}.
Bump the pkg_install version to 20050204.
Also, re-arrange to prevent the #define versions of XtoY functions
from coming before the function prototypes.
XXX This is rather ugly, and someone like kleink should probably check
that I didn't mess up any standards issues.
in some implementations (eg. sun4c), the hardware modifies the destination
reg before checking for write permission on the memory location. without
this change, gcc was using the same register for the address and the
destination, so if the store part of the instruction faulted, the address
was already gone when the instruction was retried after resolving the fault.

read faults even if the problem was that the memory was read-only.
detect this case and relabel the fault as both read and write.

Unfortunately, it conflicted with a function of the same defined in
stdlib.h. This was masked by the __P hack, which is now being purged.
I've renamed "srand" to "seedrand" to eliminate the conflict.
