The raising of exceptions from check_watchpoint, buried inside
of the I/O subsystem, is fundamentally broken. We do not have
the helper return address with which we can unwind guest state.
Replace PHYS_SECTION_WATCH and io_mem_watch with TLB_WATCHPOINT.
Move the call to cpu_check_watchpoint into the cputlb helpers
where we do have the helper return address.
This allows watchpoints on RAM to bypass the full i/o access path.

We had two different mechanisms to force a recheck of the tlb.
Before TLB_RECHECK was introduced, we had a PAGE_WRITE_INV bit
that would immediate set TLB_INVALID_MASK, which automatically
means that a second check of the tlb entry fails.
We can use the same mechanism to handle small pages.
Conserve TLB_* bits by removing TLB_RECHECK.

Preparation for collapsing the two byte swaps adjust_endianness and
handle_bswap into the former.
Call memory_region_dispatch_{read|write} with endianness encoded into
the "MemOp op" operand.
This patch does not change any behaviour as
memory_region_dispatch_{read|write} is yet to handle the endianness.
Once it does handle endianness, callers with byte swaps can collapse
them into adjust_endianness.

The xen_[rw]?mb() macros defined in ring.h can't be used and the fact
that there are gated behind __XEN_INTERFACE_VERSION__ means that it
needs to be defined somewhere. QEMU doesn't implement interfaces with
the Xen hypervisor so defining __XEN_INTERFACE_VERSION__ is pointless.
This leads to:
include/hw/xen/io/ring.h:47:5: error: "__XEN_INTERFACE_VERSION__"
is not defined, evaluates to 0 [-Werror=undef]
Cleanup ring.h. The xen_*mb() macros are already defined in xenctrl.h
which is included in xen_common.h.

Per supported platforms doc[1], the various min glib on relevant distros is:
RHEL-8: 2.56.1
RHEL-7: 2.50.3
Debian (Buster): 2.58.3
Debian (Stretch): 2.50.3
OpenBSD (Ports): 2.58.3
FreeBSD (Ports): 2.56.3
OpenSUSE Leap 15: 2.54.3
SLE12-SP2: 2.48.2
Ubuntu (Xenial): 2.48.0
macOS (Homebrew): 2.56.0
This suggests that a minimum glib of 2.48 is a reasonable target.

glib: bump min required glib library version to 2.40
This will result in us dropping support for Debian Jessie and
Ubuntu 14.04.
As per the commit message 14.04 was already outside our list
of supported build platforms and an exception was only made
because one of the build hosts used during merge testing was
stuck on 14.04.
Debian Jessie is justified to drop because we only aim to
support at most 2 major versions of Debian at any time. This
means Buster and Stretch at this time.
The g_strv_contains compat code is dropped as this API is
present since 2.44
The g_assert_cmpmem compat code is dropped as this API is
present since 2.46
