already does the initialization (though it didn't set pca_initialized, so
we always initialized twice) and since attach calls make_dev(), there's no
way that pcaopen() can be called before pcaattach().

Note: I suppose one might need to hack the hints file as well?

Forgot to mention: creation of a full-fleged package archive requires some
changes in bsd.ports.mk, because currently it doesn't install some files
that are usually packed into the package archive (+MTREE_DIRS, +DISPLAY
and so on). Support for this will be committed later.
allows for an easy way to backup old version of port prior to installing
a new one;
- silence compiler warnings by killing some unused variables and adding
all includes necessary.

because the IN_RENAME flag only fixes a few of the huge number of race
conditions that can result in the source path becoming invalid even
prior to the VOP_RENAME() call. The panics created a serious security
issue whereby an attacker could fairly easily cause the panic to
occur, crashing the machine.
The correct solution requires a great deal of work in the namei
path cache code.

Until now, the ptrace syscall was implemented as a wrapper that called
various functions in procfs depending on which ptrace operation was
requested. Most of these functions were themselves wrappers around
procfs_{read,write}_{,db,fp}regs(), with only some extra error checks,
which weren't necessary in the ptrace case anyway.
This commit moves procfs_rwmem() from procfs_mem.c into sys_process.c
(renaming it to proc_rwmem() in the process), and implements ptrace()
directly in terms of procfs_{read,write}_{,db,fp}regs() instead of
having it fake up a struct uio and then call procfs_do{,db,fp}regs().
It also moves the prototypes for procfs_{read,write}_{,db,fp}regs()
and proc_rwmem() from proc.h to ptrace.h, and marks all procfs files
except procfs_machdep.c as "optional procfs" instead of "standard".
