01df040b52 x86: Debug register emulation (Jan Kiszka) 
Built on top of previously enhanced breakpoint/watchpoint support, this
patch adds full debug register emulation for the x86 architecture.

Many corner cases were considered, and the result was successfully
tested inside a Linux guest with gdb, but I won't be surprised if one
or two scenarios still behave differently in reality.

64b4d28c38 target-alpha: implement getxuid and getxgid syscalls 
This patch implemented the setxuid and setxgid syscalls for Alpha.
These syscalls return two values, both uid/euid and gid/egid.
In addition to returning the first value in $v0, the additional
value is returned in the $a4 register.

The syscalls are used instead of the separate syscalls for those values
used on other architectures (this is probably because Alpha Linux started
out syscall compatible with DEC/OSF/Tru64).

With this patch, the perlbmk benchmarks from Spec2000 run properly.

dccfec679e target-alpha: fix termbits and target IOC macros 
This patch fixes the two following problems for Alpha linux-user:
   - termbits.h is incorrectly using host IOC macros and structures
   - IOC bitfields sizes are incorrectly set

This patch corrects the ioctl TCGETS done by isatty function call
on Alpha (when running SPEC crafty for instance).

1f9611242b target-alpha: add proper fcntl definitions 
On Alpha the target to native fcntl definitions were missing.  Because of
this, programs trying to open files with the O_CREAT option were getting
O_APPEND instead, etc.

This was keeping gcc from the spec benchmarks from running, among other
things.

glibc's structs dirent and dirent64 is different from in-kernel dirent

To avoid conflict with glibc it called struct linux_dirent(64).

a2155fcc65 Swap only altered elements of the grouplist in getgroups() (Kirill Shutemov). 
getgroups() returns the number of supplementary group IDs, so it's
unnessary to swap the entire array.  It can dramatically speed up
the syscall: on recent Linux kernels NGROUPS_MAX=65536.

a6cc84f49c Kludge to support linux-user on a PPC64 
Some headers (e.g. signal.h) include asm/elf.h and the chaos of macro
redefinitions ensues, this kludge avoids it.

Alternative way to fight that would be to change all ELF_XXX and some
other definitions to QEMU_ELF_XXX or something to that effect.

This patch concludes the quest for enabling linux-user on PPC64,
however, since qemu_mallocz uses mmap and, at least on this system,
mmap tends to return values that do not fit into 32bit, emulation for
32bit targets does not work without some hacks wich are to disgusting
to commit (and as `man mmap' tells us MAP_32BIT is only implemented on
X86_64)

The mistake was, probably, never noticed due to the absence of any
big endian linux-user host. The types e1/e2 and p begs the quesiton
why this function takes longs at all.
