reduce ABI disruptions when new cpu types and new PMC events are added
in the future.
- Support alternate spellings for PMC events. Derive the canonical
spelling of an event name from its enumeration name in 'enum pmc_event'.
- Provide a way for users to disambiguate between identically named events
supported by multiple classes of PMCs in a CPU.
- Change libpmc's machine-dependent event specifier parsing code to
better support CPUs containing two or more classes of PMC resources.
- Pass O_NOCTTY to posix_openpt(2). This makes the implementation work
consistently on implementations that make the PTY the controlling TTY
by default.
- Call unlockpt() before opening the slave device. POSIX mentions that
de slave device should only be opened after grantpt() and unlockpt()
have been called.
- Replace some redundant code by a label.
In theory we could remove a lot of code from openpty() on FreeBSD
-CURRENT, because grantpt(), unlockpt() and revoke() are not needed in
our implementation. We'd better keep them there. This makes the code
still work with older FreeBSD releases and even makes it work on other
non-BSD operating systems.
I've compiled openpty() on Linux. You only need to remove the revoke()
call, because revoke() on Linux always returns -1. Apart from that, it
seems to work like it should.

where critical. Some places still use ps_pread/ps_pwrite directly,
but only need changed when byte-order comes into the picture.
Also, change th_p in td_event_msg_t from a pointer type to
psaddr_t, so that events also work when psaddr_t is widened.
review by secteam@ for the reasons mentioned below.
1) Rename /dev/urandom to /dev/random since urandom marked as

alias in /sys/dev/random/randomdev.c
(this is our naming convention and no review by secteam@ required)
2) Set rs_stired flag after forced initialization to prevent
double stearing.
(this is already in OpenBSD, i.e. they don't have double stearing.
It means that this change matches their code path and no additional
secteam@ review required)
