a5f50ef9e4 netchild's mega-patch to isolate compiler dependencies into a central
place.

This moves the dependency on GCC's and other compiler's features into
the central sys/cdefs.h file, while the individual source files can
then refer to #ifdef __COMPILER_FEATURE_FOO where they by now used to
refer to #if __GNUC__ > 3.1415 && __BARC__ <= 42.

By now, GCC and ICC (the Intel compiler) have been actively tested on
IA32 platforms by netchild.  Extension to other compilers is supposed
to be possible, of course.

a122cca953 These are changes to allow to use the Intel C/C++ compiler (lang/icc)
to build the kernel. It doesn't affect the operation if gcc.

Most of the changes are just adding __INTEL_COMPILER to #ifdef's, as
icc v8 may define __GNUC__ some parts may look strange but are
necessary.

Additional changes:
 - in_cksum.[ch]:
   * use a generic C version instead of the assembly version in the !gcc
     case (ASM code breaks with the optimizations icc does)
     -> no bad checksums with an icc compiled kernel
     Help from:		andre, grehan, das
     Stolen from: 	alpha version via ppc version
     The entire checksum code should IMHO be replaced with the DragonFly
     version (because it isn't guaranteed future revisions of gcc will
     include similar optimizations) as in:

   Suggested by:	bde (long ago)
 - assym.h:
   * avoid zero-length arrays (remove dependency on a gcc specific
     feature)
     This change changes the contents of the object file, but as it's
     only used to generate some values for a header, and the generator
     knows how to handle this, there's no impact in the gcc case.

 - aicasm.c:
   * minor change to teach it about the way icc spells "-nostdinc"
   Not approved by:	gibbs (no reply to my mail)
 - bump __FreeBSD_version (lang/icc needs to know about the changes)

Incarnations of this patch survive gcc compiles since a loooong time,
I use it on my desktop. An icc compiled kernel works since Nov. 2003
(exceptions: snd_* if used as modules), it survives a build of the
entire ports collection with icc.

Parts of this commit contains suggestions or submissions from
Marius Strobl <marius@alchemy.franken.de>.

c4ff2eb1dd Newly implemented ioctls list:
DIOCGDINFO, DIOCGPART, DIOCWDINFO, DIOCSDINFO, CDIOCPLAYMSF, CDIOCRESET,
CDIOCEJECT.

CDIOCPLAYBLOCKS removed (old implementation completely wrong and I don't
know how to implement it correctly).

All routines now detects media change correctly.

DELAY_GETREPLAY increased for long time access from first track
to last.

mcd_waitrdy() now use MIN_DELAY=15 as minimal delay which independs
of machine speed.

mcd_doread() now uses real status (old code uses obsoleted soft copy of it).

clear XBSY on error in mcd_doread()

mcd_statrt(): add missing splx(s), cause dead hang with unmatched slpbio()

optimize mcd_doread(), don't set CD mode each time, keep soft copy of mode.

call getdisklabel() _after_ mcdsize() for proper sizes

mcdopen(): old code forget to set MCDREADRAW in flags when open RAW
partition, doread check it for setting RAW CD mode.

Do nothing on stray interrupt (which sometimes occurse, because driver
read data block too slow, DOS driver use 'insb' here). Old stray code
cause timeouts.

Read toc entries code rewritten to return many requested entries
(as supposed) instead of one entry with incorrect structure.

CMDREAD2 requests covered with disable_intr()/enable_intr()
(from DOS driver)

Read junk code added after read block code in doread (from DOS driver)

mcd_read_toc() code fixed to read all needed entries, old code cause
some audio tracks is not played.

mcd_playtracks() code fixed to proper check valid track range.

New binary read modes implemented (from DOS driver).
