target-i386: mmu: fix handling of noncanonical virtual addresses
mmu_translate is supposed to return an error code for page faults; it is
not able to handle other exceptions. The #GP case for noncanonical
virtual addresses is not handled correctly, and incorrectly raised as
a page fault with error code 1. Since it cannot happen for nested
page tables, move it directly to handle_mmu_fault, even before the
invocation of mmu_translate.
Fixes: #676

Log Message:

meson: perform snappy test with the C++ compiler if used
Snappy is written in C++ and as such needs to link against libstdc++. When
linking statically, this means that the compile test cannot succeed unless
performed with a C++ compiler. Do so if link_language is set to C++; if it
is C, the test will usually fail and snappy will be disabled.

$TARGET_NAME-config-devices.h files are now generated by
configure_file() rather than scripts/create_config. Adjust
he relevant paragraph in docs/devel/build-system.rst, and take
the occasion to fix a preexisting confusion of *.h vs *.mak.

configure: simplify calls to meson_quote
meson_quote assumes a non-empty argument list, and incorrectly returns a
one-entry array if passed nothing. Move the check for an empty argument
list from the invocations to the function itself.

Log Message:
-----------
configure: preserve CFLAGS, CXXFLAGS and LDFLAGS in config.status
CFLAGS, CXXFLAGS and LDFLAGS influence the tests (for example if they include
-L or -I options), so they should be kept from the invocation of configure
to the subsequent reinvocations via config.status.

Log Message:
-----------
configure: propagate --extra-cflags and --extra-ldflags to meson compile tests
Meson (intentionally) does not add QEMU_CFLAGS to cc.compiles/cc.links
tests, as they are supposed to be independent of the specific sets of
compilation flags used to build the programs. However, the user can
still use CFLAGS or the toolchain file's LANG_args/LANG_link_args option
to specify -I or -L options that apply to cc.compiles/cc.links as well.
This is also the intended use of configure's --extra-cflags,
--extra-cxxflags and --extra-ldflags options. For example, if
one has netmap's header in a nonstandard directory, up to commit
837b84b1c078bf3e909 it used to work fine to do:
.../configure --enable-netmap \
--extra-cflags=-I/path/to/netmap/sys
but since the test was converted to meson, this does not work anymore.
Pass these options to meson via the toolchain file instead of via
config-host.mak, since both have the same purpose.

User flags should be passed via CFLAGS/CXXFLAGS/LDFLAGS,

command line.
QEMU_CFLAGS, QEMU_CXXFLAGS and QEMU_LDFLAGS are reserved
for flags detected by configure, so do not add to them
and clear them at the beginning of the script.
