accel/tcg: Relax va restrictions on 64-bit guests
...
We cannot at present limit a 64-bit guest to a virtual address
space smaller than the host. It will mostly work to ignore this
limitation, except if the guest uses high bits of the address
space for tags. But it will certainly work better, as presently
we can wind up failing to allocate the guest stack.
Widen our user-only page tree to the host or abi pointer width.
Remove the workaround for this problem from target/alpha.
Always validate guest addresses vs reserved_va, as there we
control allocation ourselves.

gdbstub/linux-user: support debugging over a unix socket
...
While debugging over TCP is fairly straightforward now we have test
cases that want to orchestrate via make and currently a parallel build
fails as two processes can't use the same listening port. While system
emulation offers a wide cornucopia of connection methods thanks to the
chardev abstraction we are a little more limited for linux user.
Thankfully the programming API for a TCP socket and a local UNIX
socket is pretty much the same once it's set up.

memory: Do not allow direct write access to rom_device regions
...
According to the documentation in memory.h a ROM memory region will be
backed by RAM for reads, but is supposed to go through a callback for
writes. Currently we were not checking for the existence of the rom_device
flag when determining if we could perform a direct write or not.
To correct that add a check to memory_region_is_direct so that if the
memory region has the rom_device flag set we will return false for all
checks where is_write is set.
