41a3e3b022 Update manual page to reflect changes in rev 1.12 of
"src/lib/libc/gen/popen.c" --- popen() in the child
now closes any copies of popen()'ed descriptors in the parent.

842a95cc23 First of a series of cleanups to libfetch. Changed files, in
alphabetical order:

 Makefile:
  Add common.c to SRCS.

  Make debugging easier by making 'CFLAGS += -DNDEBUG' conditional on DEBUG

  Don't declare struct {ftp,http}err in {ftp,http}err.c; use struct fetcherr
  instead.

 README:
  Remove the todo list, which is out of date anyway.

 common.c: (new file)
  Gather utility functions in this file.

  Merge the error reporting functions intp _fetch_errstring(),
  _fetch_seterr() and _fetch_syserr().

  Set fetchLastErrCode and fetchLastErrText appropriately when fetchConnect
  fails.

 common.h: (new file)
  Gather internal prototypes and structures in this files.

 fetch.3:
  Undocument fetchFreeURL().

  Document a few more known bugs.

  Document fetchLastErrCode and fetchLastErrText.

 fetch.c:
  Add descriptive comments to all functions that lacked them.

  Move fetchConnect() to common.c.

  Obviate the need for fetchFreeURL(), and remove it.

 fetch.h:
  Modify struct url_t so the document part is at the end.

 ftp.c:
  Remove code that is duplicated elsewhere.

 http.c:
  Remove code that is duplicated elsewhere.

b8ffd2a51c Well I never. Seems like _setjmp()/_longjmp() are just what the doctor
ordered.  This brings the Alpha back to parity, and should bring us
BootForth on both platforms.

25c3957dfd Move setjmp/longjmp implementations here from libc; no signal handling
in libstand, only for i386 until I locate an alpha setjmp/longjmp.

Minimal 64-bit gcc integer support for i386.  This is kinda nasty, and
should be revisited once we decide whether the bootblocks need
quad arithmetic.

86854f0360 A feeble attempt at kld compatability. The mount_* programs assume that
they cannot mount a filesystem that they cannot see in getvfsbyname().
Part 1 of this is a hack, make vfsisloadable() always return true - the
ultimate decider of whether it's loadable or not is kldload() or mount().
Part 2 of this is to have vfsload() call kldload(2) and return success if
it works.  This means that we will use a viable kld module in preference
to an LKM!
Ultimately, the thing to do is remove the hacks to do a vfsload in all the
mount_* commands and let the kernel do it by itself in mount(2).

d58fb9293a To clarify last commit, msmith says:
The reason the Alpha has less room than the i386 is because the bootstrap
is given a 256K mapping by the firmware; to add more requires extra work.

01a4eb824c Add man pages for many of the functions in the CAM library. This covers
most of the open/close routines, and the buffer/cdb parsing routines
derived from the old scsi(3) library.

The cam_cdbparse(3) man page borrows from the old scsi(3) man page, so the
copyright and history section reflect that.

The many scsi_* functions and other functions that are pulled in from the
kernel aren't documented yet, but will be eventually.

1fd98d7d88 Calls one or more of malloc(), warn(), err(), syslog(), execlp() or
execvp() in the child branch of a vfork(). Changed to use fork()
instead.

Some of these (mv, find, apply, xargs) might benefit greatly from
being rewritten to use vfork() properly.

13a5277c23 Fix a curses bug exposed by the ":numbers" display of systat -iostat.
This bug showed up when you had more than 3 devices displayed.  (thus
requiring a second line of display)

Here's a quote From the PR:

 When wrefresh() is called with a subwindow as argument, __set_subwin
 might be called with reversed arguments if wrefresh() decides to calls
 quickch().  This may cause use of negative array indexes, with a
 resulting segfault.

 Since quickch() manipulates the line structures belonging to curscr,
 it looks like all subwindows of curscr should be updated.
