At least for Linux distributions UTF-8 is now standard,
so the QEMU documentation should use this encoding, too.
Even if there was currently only a single special character
using ISO-8859-1, this might change in the future.
So the texinfo keywords @documentlanguage and
@documentencoding now document the language and the
encoding. The special character was changed to UTF-8
(it could also have been changed to an x, but the
original cross looks really nice if it is displayed
correctly).
These changes fix the html presentation at
http://www.qemu.org/qemu-doc.html#SEC65
(ARM System emulator).

Clean up the current mess about figuring out which flags to pass to the
driver. BDRV_O_FILE, BDRV_O_SNAPSHOT and BDRV_O_NO_BACKING are flags
only used by the block layer internally so filter them out directly.
Previously BDRV_O_NO_BACKING could accidentally be passed to the drivers,
but wasn't ever used.

This commit introduces the bdrv_mon_event() function, which
should be called by block subsystems (eg. IDE) when a I/O
error occurs, so that an QMP event is emitted.
The following information is currently provided in the event:
- device name
- operation (ie. "read" or "write")
- action taken (eg. "stop")
Event example:
{ "event": "BLOCK_IO_ERROR",
"data": { "device": "ide0-hd1",
"operation": "write",
"action": "stop" },
"timestamp": { "seconds": 1265044230, "microseconds": 450486 } }

Makefile already supported dvi, html and info formats,
but pdf was missing.
pdf is especially convenient for printing and for
documentation reviews. I hope it will help to
improve qemu's documentation.
Make now supports the new target 'pdf' which will
create qemu-doc.pdf and qemu-tech.pdf. It is also
possible to build both files individually.
texi2pdf and texi2dvi are rather noisy, so normally
some less important warnings are suppressed.
When make is called with V=1 (verbose mode),
warnings are not suppressed.
The patch also sorts the documentation targets
alphabetically and wraps a line which was too long.

On SH4, the ITLB and UTLB configurations are memory mapped, so loading
ITLB entries from UTLB has to be simulated correctly. For that the QEMU
TLB has to be handle the execute (ITLB) and read/write permissions
(UTLB) seperately.
Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
With the current code, the QEMU TLB is setup to match the read/write
mode of the MMU fault. This means when read access is done, the page
is setup in read-only mode. When the page is later accessed in write
mode, an MMU fault happened, and the page is switch in write-only
mode. This flip-flop causes a lot of calls to the MMU code and slow
down the emulation.
This patch changes the MMU emulation, so that the QEMU TLB is setup
to match the UTLB protection key. This impressively increase the
speed of the emulation.
