util/qemu-openpty: fix build with musl libc by include termios.h as fallback
Include termios.h as POSIX fallback when not glibc, bsd or solaris.
POSIX says that termios.h should define struct termios and TCAFLUSH.
http://pubs.opengroup.org/onlinepubs/
9699919799/basedefs/termios.h.html
This fixes the following compile errors with musl libc:

bsd-user/mmap.c: Don't try to override g_malloc/g_free
Trying to override the implementations of g_malloc and g_free is
a really bad idea -- it means statically linked builds fail to
link (because of the multiple definitions provided by this file
and by glib), and non-statically linked builds segfault as soon
as they try to do anything more complicated than printing the
usage message. Remove these overridden versions and just use
the glib ones.

target-arm: Fix errors in writes to generic timer control registers
The code for handling writes to the generic timer control registers
had several bugs:
* ISTATUS (bit 2) is read-only but we forced it to zero on any write
* the check for "was IMASK (bit 1) toggled?" incorrectly used '&' where
it should be '^'
* the handling of IMASK was inverted: we should set the IRQ if
ISTATUS is set and IMASK is clear, not if both are set
The combination of these bugs meant that when running a Linux guest
that uses the generic timers we would fairly quickly end up either
forgetting that the timer output should be asserted, or failing to
set the IRQ when the timer was unmasked. The result is that the guest
never gets any more timer interrupts.

target-arm: Correct handling of UXN bit in ARMv8 LPAE page tables
In v8 page tables bit 54 in the PTE is UXN in the EL0/EL1 translation regimes
and XN elsewhere. In v7 the bit is always XN. Since we only emulate EL0/EL1 we
can just treat this bit as UXN whenever we are in v8 mode.
Also correctly extract the upper attributes from the PTE entry, the v8 version
tried to avoid extracting the CONTIG bit and ended up with the upper bits being
off-by-one. Instead behave the same as v7 and extract (but ignore) the CONTIG
bit.

vexpress: Add support for the -bios flag to provide firmware
Right now to run firmware inside the QEMU VExpress model requires
padding out the firmware image to the size of the virtual flash and
passing it in via the -pflash argument. If the firmware image is passed
without padding, then QEMU will fail. Also, when passed as a -pflash
argument, QEMU treats the file as persistent storage and will modify the
file.
The -bios flag provides the semantics that we want for providing a
firmware image. This patch maps the contents of the -bios file into the
address space at the boot flash location.

sheepdog: fix vdi object update after live snapshot
sheepdog driver should decide a write request is COW or not based on inode
object which is active when the write request is issued.
Example of wrong inode update path in the previous driver:
1. drier issues an ordinal write request to an existing object
2. user creates a snapshot of the VDI before the write request is completed
3. the respones for the request is RDONLY, because the VDI is already a snapshot
4. the driver reload an inode object of the new active VDI, then issues a write
request again
5. the second write request can be completed
6. driver decide the request is COW or not with the below conditional branch:
if (s->inode.data_vdi_id[idx] != s->inode.vdi_id) {
7. the ID of the written object and VID of the new active VDI is different, so
the driver updates data_vdi_id[idx] and writes inode object
8. the existing object cannot be seen by the new active VDI, it results object
leaking

While the registers are documented as being 64-bit, Linux seems to access
them in two halves as 2 x 32-bit accesses. Make sure that we can correctly
handle this case.
