f257b7a54b Make VFS_ROOT() and vflush() take a thread argument.
This is to allow filesystems to decide based on the passed thread
which vnode to return.
Several filesystems used curthread, they now use the passed thread.

507b03186a Change kse_switchin to accept kse_thr_mailbox pointer, the syscall
will be used heavily in debugging KSE threads. This breaks libpthread
on IA64, but because libpthread was not in 5.2.1 release, I would like
to change it so we needn't to introduce another syscall.

e5996857ad Make regular expression matching aware of multibyte characters. The general
idea is that we perform multibyte->wide character conversion while parsing
and compiling, then convert byte sequences to wide characters when they're
needed for comparison and stepping through the string during execution.

As with tr(1), the main complication is to efficiently represent sets of
characters in bracket expressions. The old bitmap representation is replaced
by a bitmap for the first 256 characters combined with a vector of individual
wide characters, a vector of character ranges (for [A-Z] etc.), and a vector
of character classes (for [[:alpha:]] etc.).

One other point of interest is that although the Boyer-Moore algorithm had
to be disabled in the general multibyte case, it is still enabled for UTF-8
because of its self-synchronizing nature. This greatly speeds up matching
by reducing the number of multibyte conversions that need to be done.

fbc3247d81 Implement the PT_LWPINFO request. This request can be used by the
tracing process to obtain information about the LWP that caused the
traced process to stop. Debuggers can use this information to select
the thread currently running on the LWP as the current thread.

The request has been made compatible with NetBSD for as much as
possible. This implementation differs from NetBSD in the following
ways:
1.  The data argument is allowed to be smaller than the size of the
    ptrace_lwpinfo structure known to the kernel, but not 0. This
    is opposite to what NetBSD allows. The reason for this is that
    we can extend the structure without affecting older binaries.
2.  On NetBSD the tracing process is to set the pl_lwpid field to
    the Id of the LWP it wants information of. We don't do that.
    Our ptrace interface allows passing the LWP Id instead of the
    PID. The tracing process is to set the PID to the LWP Id it
    wants information of.
3.  When the PID is actually the PID of the tracing process, this
    request returns the information about the LWP that caused the
    process to stop. This was the whole purpose of the request in
    the first place.

When the traced process has exited, this request will return the
LWP Id 0, indicating that the process state is not the result of
an event specific to a LWP.

98c151d6d9 Cache a pointer to the old proc (as well as negative cache) to make
computing the io statistics over and over not as expensive.
This is a bit of a cop out, as I should just allocate a struct with
the computed values, but this will do for now.

f3be7cb3e9 Re-add the gdb command. It was removed to be replaced by something
more generic, but that didn't actually happen. Since the feature to
switch backends (and historically this means from DDB to GDB) is
important, make sure people can do just that until such the generic
mechanism actually sees the light of day.

a294c3664f Use sockbuf_pushsync() to synchronize stack and socket buffer state
in soreceive() after removing an MT_SONAME mbuf from the head of the
socket buffer.

When processing MT_CONTROL mbufs in soreceive(), first remove all of
the MT_CONTROL mbufs from the head of the socket buffer to a local
mbuf chain, then feed them into dom_externalize() as a set, which
both avoids thrashing the socket buffer lock when handling multiple
control mbufs, and also avoids races with other threads acting on
the socket buffer when the socket buffer mutex is released to enter
the externalize code.  Existing races that might occur if the protocol
externalize method blocked during processing have also been closed.

Now that we synchronize socket buffer and stack state following
modifications to the socket buffer, turn the manual synchronization
that previously followed control mbuf processing with a set of
assertions.  This can eventually be removed.

The soreceive() code is now substantially more MPSAFE.

b7562e178c Add sockbuf_pushsync(), an inline function that, following a change to
the head of the mbuf chains in a socket buffer, re-synchronizes the
cache pointers used to optimize socket buffer appends.  This will be
used by soreceive() before dropping socket buffer mutexes to make sure
a consistent version of the socket buffer is visible to other threads.

While here, update copyright to account for substantial rewrite of much
socket code required for fine-grained locking.

d861372b14 Add additional annotations to soreceive(), documenting the effects of
locking on 'nextrecord' and concerns regarding potentially inconsistent
or stale use of socket buffer or stack fields if they aren't carefully
synchronized whenever the socket buffer mutex is released.  Document
that the high-level sblock() prevents races against other readers on
the socket.

Also document the 'type' logic as to how soreceive() guarantees that
it will only return one of normal data or inline out-of-band data.

35e454b36c MFi386: rev 1.213 -- fix DELAY while the debugger is active.
This also fixes the (runtime) breakage introduced in the previous
commit that was the result of a botched merge. This hasn't even
been compile-tested...

45cfc0a914 Partially revert previous commit. Calling getit() unconditionally fixed
a problem that could also be fixed differently without reverting previous
attempts to fix DELAY while the debugger is active (rev 1.204). The bug
was that the i8254 implements a countdown timer, while for (k)db_active
a countup timer was implemented. This resulted in premature termination
and consequently the breakage of DELAY. The fix (relative to rev 1.211)
is to implement a countdown timer for the kdb_active case. As such the
ability to step clock initialization is preserved and DELAY does what is
expected of it.
