Abstract out the "print a human readable list of all the
valid log categories" functionality which is currently duplicated
in three separate places. (We leave the monitor.c help_cmd()
implementation as-is since it wants to send the message to
the monitor and add its own information.)

The qemu_log() functionality is no longer specific to TCG CPU debug logs.
Rename cpu_set_log_filename() to qemu_set_log_filename() and drop the
pointless wrapper set_cpu_log_filename().

It's worth to clean-up translation blocks variables and move them
into one context as was suggested by Swirl.
Also if we use this context directly inside tcg_ctx, then it
speeds up code generation a bit.

Commit 658f2dc97 accidentally dropped the cast to the target type of
the value loaded by get_user(). The most visible effect of this would
be that the sequence "uint64_t v; get_user_u32(v, addr)" would sign
extend the 32 bit loaded value into v rather than zero extending as
would be expected for a _u32 accessor. Put the cast back again to
restore the old behaviour.

Since commit 65dee38052597b6285eb208125369f01b29ba6c1 (target-i386:
move cpu_reset and reset callback to cpu.c) the x86 CPU is reset through
cpu_init() but was still reset immediately after in linux-user and
bsd-user. Clean this up.
Similarly in linux-user/syscall.c it is also reset after cpu_copy().
But that's a bug of its own, fixing which poses a semantic change.

this declaration is wrong:
the correct prototype on linux is:
int setgroups(size_t size, const gid_t *list);
since by default musl libc exposes this symbol in unistd.h
additionally to grp.h, the wrong declaration causes a build error.
the proper fix is to simply include the correct header.

The Linux syscalls underlying pread() and pwrite() take a 64 bit
offset on all architectures, even if some of them name the syscall
"pread/pwrite" rather than "pread64/pwrite64" for historical reasons.
So move the four QEMU target architectures (arm, i386, sparc,
unicore32) which were defining TARGET_NR_pread/pwrite to define
TARGET_NR_pread64/pwrite64 instead, and drop the TARGET_NR_pread/pwrite
implementation code completely.
(Based on examination of the kernel sources for the four architectures
this patch affects.)

The statfs syscall should always memset(0) its full struct extent before
