a2953f767d MFV: Update zlib to 1.2.7.
(x86 assembler optimization disabled for now because it
requires the new .cfi_* directives that is not supported
by base system binutils).

7f725bcd5c Import work done under project/nand (@235533) into head.
The NAND Flash environment consists of several distinct components:
  - NAND framework (drivers harness for NAND controllers and NAND chips)
  - NAND simulator (NANDsim)
  - NAND file system (NAND FS)
  - Companion tools and utilities
  - Documentation (manual pages)

This work is still experimental. Please use with caution.

b3608ae18f Replace index() and rindex() calls with strchr() and strrchr().
The index() and rindex() functions were marked LEGACY in the 2001
revision of POSIX and were subsequently removed from the 2008 revision.
The strchr() and strrchr() functions are part of the C standard.

This makes the source code a lot more consistent, as most of these C
files also call into other str*() routines. In fact, about a dozen
already perform strchr() calls.

46632c18bd Merge index() and strchr() together.
As I looked through the C library, I noticed the FreeBSD MIPS port has a
hand-written version of index(). This is nice, if it weren't for the
fact that most applications call strchr() instead.

Also, on the other architectures index() and strchr() are identical,
meaning we have two identical pieces of code in the C library and
statically linked applications.

Solve this by naming the actual file strchr.[cS] and let it use
__strong_reference()/STRONG_ALIAS() to provide the index() routine. Do
the same for rindex()/strrchr().

This seems to make the C libraries and static binaries slightly smaller,
but this reduction in size seems negligible.

cb301c1a81 Add placeholder code for prepending pathnames to tftp.
At work we have a single tftp server that provides installation data for
a variety of operating systems. I'd rather place our FreeBSD-related
files in a subdirectory, instead of the root.

It would be nice if this setting could be run-time configurable, but at
least in our specific case, this is not possible, as pxeboot is
chainloaded through pxelinux.

f497fbf5e4 - Removing some unneeded definitions of NULL(cruft related to 1970's C).
In C90, NULL is guaranteed to be declared in <stddef.h> and also in
  <string.h>.  Though the correct way to define NULL in FreeBSD is to
  include <sys/_null.h>, other parts of libstand still require <string.h>
  to build; therefore, we keep <string.h> in stand.h and add a note about
  this;
- Removing no longer used 'Prototype' definition.  Quote from bde@:

	'Cruft related to getting incomplete struct declarations within
	prototypes forward-declared before the structs.  It doesn't mean
	"prototype" but only part of a prototype-related hack.  No longer
	used.'

- Replacing iaddr_t with uintptr_t;
- Removing use of long double to determine alignment.  Use a fixed 16 byte
  alignment instead;

728fc2d633 Fixing building bustage on 32 bits platforms when WARNS >= 2. Note that
this fix only applies to zalloc.c, the other part of libstand such like
qdivrem.c still gives compilation warnings on sparc64 tinderbox builds;
therefore, WARNS level isn't changed for now.

23a5bce73f Fixes to newer tftp code in libstand:
(1) Coding style changes.
 (2) If the server does not acknowledge any blocksize option,
     revert to the default blocksize of 512 bytes.
 (3) Send ACK if the first packet happens to be the last packet.
 (4) Do not accept blocksize greater than what was requested.
 (5) Drop any unwanted OACK received if a tftp transfer is already
     in progress.
 (6) Terminate incomplete transfers with a special no-error ERROR packet.
     Otherwise we rely on the tftp server to time out, which it does
     eventually, after re-sending the last packet several times and spamming
     the system log about it every time.  This idea is borrowed from the
     PXE client, which does exactly that.

32ecdb308f Bring back following change which was undone in previous commit:
------------------------------------------------------------------------
    r172854 | marius | 2007-10-21 10:03:18 -0700 (Sun, 21 Oct 2007) | 16 lines
    Changed paths:
       M /head/lib/libstand/tftp.c

    - Given that we tell the compiler that struct ip is packed and 32-bit
      aligned, GCC 4.2.1 also generates code for sendudp() that assumes
      this alignment. GCC 4.2.1 however doesn't 32-bit align wbuf, causing
      the loader to crash due to an unaligned access of wbuf in sendudp()
      when netbooting sparc64. Solve this by specifying wbuf as packed and
      32-bit aligned, too. As for lastdata and readudp() this currently is
      no issue when compiled with GCC 4.2.1, though give lastdata the same
      treatment as wbuf for consistency and possibility of being affected
      in the future. [1]
    - Sprinkle const on a lookup table.

4c474d5c2f (1) When sending the TFTP RRQ packet to read a file,
send along the "blksize" option specified in RFC2348,
     and the "tsize" option specified in RFC2349.

     Add code to parse the TFTP Option Acknowledgement (OACK) packet as
     specified in RFC2347.

     For TFTP servers which support the "blksize" option, we can
     specify a TFTP Data block size larger than the default 512 bytes
     specified in RFC1350.  This offers greater read performance when
     downloading files.

     We request an initial size of 1428 bytes, which is less than the
     Ethernet MTU of 1500 bytes.  If the TFTP server sends back an OACK
     packet, then use the block size specified in the OACK packet.
     Most times it is usually the same value as what we request.
     If the TFTP server supports RFC2348, we will see performance improvements
     by transferring files over TFTP with larger block sizes.

     If we do not get back an OACK packet, then we most likely we
     are interoperating with a legacy TFTP server that does not
     support TFTP extension options, so default to the block size of
     512 bytes.

(2)  If the "tftp.blksize" environment variable is set, then
     take that value and use it when sending the TFTP RRQ packet,
     instead of 1428.  This allows us to set different values of
     "tftp.blksize" in the loader, so that we can test out different
     TFTP block sizes at run time.

in FreeBSD. If built with OLD_NFSV2 defined, the old
code that predated this patch will be built and NFSv2
will be used.

5cd8ebeb32 Sync. printf() of libstand(3) with sys/kern/subr_prf.c.
CVS r1.94	jhb:
Cast the integer read as the first argument for %b to an unsigned integer
so it's value is not sign extended when assigned to the uintmax_t variable
used internally by printf.  For example, if bit 31 is set in the cpuid
feature word, then %b would print out the initial value as a 16 character
hexadecimal value.  Now it only prints out an 8 character value.

CVS r1.109	njl:
Add support for 'h' and 'hh' modifiers for printf(9).

CVS r1.117	phk:
If we ignore an unknown % sequence, we must stop interpreting the remaining
% arguments because the varargs are now out of sync and there is a risk that
we might for instance dereference an integer in a %s argument.

SVN r209836	jkim:
Implement optional 'precision' for numbers.  Previously, it was parsed but
ignored.  Some third-party modules (e.g., APCICA) prefer this format over
zero padding flag '0'.
