92cc3aaa1f i386: hvf: Remove hvf_disabled
accel_init_machine sets *(acc->allowed) to true if acc->init_machine(ms)
succeeds. There's no need to have both hvf_allowed and hvf_disabled.

b4e1af8961 i386: hvf: Fix register refs if REX is present
According to Intel(R)64 and IA-32 Architectures Software Developer's
Manual, the following one-byte registers should be fetched when REX
prefix is present (sorted by reg encoding index):
AL, CL, DL, BL, SPL, BPL, SIL, DIL, R8L - R15L

The first 8 are fetched if REX.R is zero, the last 8 if non-zero.

The following registers should be fetched for instructions without REX
prefix (also sorted by reg encoding index):
AL, CL, DL, BL, AH, CH, DH, BH

Current emulation code doesn't handle accesses to SPL, BPL, SIL, DIL
when REX is present, thefore an instruction 40883e "mov %dil,(%rsi)" is
decoded as "mov %bh,(%rsi)".

That caused an infinite loop in vp_reset:

38272f2d02 Drop unneeded system header includes
<memory.h> is a non-standard obsolete header that was long ago
replaced by <string.h>.

<malloc.h> is a non-standard header; it is not obsolete (we must
use it for malloc_trim, for example), but generally should not
be used in files that just need malloc() and friends, where
<stdlib.h> is the standard header.

And since osdep.h already guarantees string.h and stdlib.h, we
can drop these unusual system header includes as redundant
rather than replacing them.

8f0a3716e4 Clean up includes
Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.

This commit was created with scripts/clean-includes, with the change
to target/s390x/gen-features.c manually reverted, and blank lines
around deletions collapsed.

d8e39b7062 Use #include "..." for our own headers, <...> for others
System headers should be included with <...>, our own headers with
"...".  Offenders tracked down with an ugly, brittle and probably
buggy Perl script.  Previous iteration was commit a9c94277f0.

Delete inclusions of "string.h" and "strings.h" instead of fixing them
to <string.h> and <strings.h>, because we always include these via
osdep.h.

Put the cleaned up system header includes first.

While there, separate #include from file comment with exactly one
blank line.
