m25p80.c: Use QOM classes for part differentiation

Currently, M25P80 uses an object property to differentiate between flash parts.
Changed this over to use QOM sub-classes - the actual names of the different parts
are used to create a set of dynamic classes which passes the part info as class
data. The object no longer needs to search the known_devices table for itself,
instead it just gets its info from its own class.

Kept the intermediate class definition private to m25p80.c for the moment, as
the expectation is parts will only be added as new entries in the table. We can
factor out the TYPE_M25P80 abstraction into a header on a demand basis.

hw/pflash_cfi01: Treat read in unknown command state as read

The code for handling the default "unknown command state" case in
pflash_read in pflash_cfi01.c comments "reset state & treat it as
a read". However the code doesn't actually do this. Moving the

makes the code behave as the comments suggest.

The pflash_cfi01 code has always had this bug -- it was presumably

qemu-log: default to stderr for logging output

Switch the default for qemu_log logging output from "/tmp/qemu.log"
to stderr. This is an incompatible change in some sense, but logging
is mostly used for debugging purposes so it shouldn't affect production
use. The previous behaviour can be obtained by adding "-D /tmp/qemu.log"
to the command line.

This change requires us to:
 * update all the documentation/help text (we take the opportunity
   to smooth out minor inconsistencies between the phrasing in
   linux-user/bsd-user/system help messages)

   logging destination rather than overriding it themselves
 * ensure that all logfile closing is done via qemu_log_close()
   and that that function doesn't close stderr
as well as the obvious change to the behaviour of do_qemu_set_log()
when no logfile name has been specified.

arm/translate.c: Fix adc_CC/sbc_CC implementation

commits 49b4c31efcce45ab714f286f14fa5d5173f9069d and
2de68a4900ef6eb67380b0c128abfe1976bc66e8 reworked the implementation of adc_CC
and sub_CC. The new implementations (on the TCG_TARGET_HAS_add2_i32 code path)
are incorrect. The new logic is:

CF:NF = 0:A +/- 0:CF
CF:NF = CF:A +/- 0:B

The lower 32 bits of the intermediate result stored in NF needs to be passes
into the second addition in place of A (s/CF:A/CF:NF):

CF:NF = 0:A +/- 0:CF
CF:NF = CF:NF +/- 0:B

This patch fixes the issue.

Replace all setjmp()/longjmp() with sigsetjmp()/siglongjmp()

The setjmp() function doesn't specify whether signal masks are saved and
restored; on Linux they are not, but on BSD (including MacOSX) they are.
We want to have consistent behaviour across platforms, so we should
always use "don't save/restore signal mask" (this is also generally
going to be faster). This also works around a bug in MacOSX where the
signal-restoration on longjmp() affects the signal mask for a completely
different thread, not just the mask for the thread which did the longjmp.
The most visible effect of this was that ctrl-C was ignored on MacOSX
because the CPU thread did a longjmp which resulted in its signal mask
being applied to every thread, so that all threads had SIGINT and SIGTERM
blocked.

The POSIX-sanctioned portable way to do a jump without affecting signal
masks is to siglongjmp() to a sigjmp_buf which was created by calling
sigsetjmp() with a zero savemask parameter, so change all uses of
setjmp()/longjmp() accordingly. [Technically POSIX allows sigsetjmp(buf, 0)
to save the signal mask; however the following siglongjmp() must not
restore the signal mask, so the pair can be effectively considered as
"sigjmp/longjmp which don't touch the mask".]

For Windows we provide a trivial sigsetjmp/siglongjmp in terms of
setjmp/longjmp -- this is OK because no user will ever pass a non-zero
savemask.

The setjmp() uses in tests/tcg/test-i386.c and tests/tcg/linux-test.c
are left untouched because these are self-contained singlethreaded
test programs intended to be run under QEMU's Linux emulation, so they
have neither the portability nor the multithreading issues to deal with.
