9568b511c9 block: Introduce a new API bdrv_co_no_copy_on_readv()
In some cases, we need to disable copy-on-read, and just
read the data.

18a8056e0b block/nfs: cache allocated filesize for read-only files
If the file is readonly its not expected to grow so
save the blocking call to nfs_fstat_async and use
the value saved at connection time. Also important
the monitor (and thus the main loop) will not hang
if block device info is queried and the NFS share
is unresponsive.

717171bd20 docs: describe the QEMU build system structure / design
Developers who are new to QEMU, or have a background familiarity
with GNU autotools, can have trouble getting their head around the
home-grown QEMU build system. This document attempts to explain
the structure / design of the configure script and the various
Makefile pieces that live across the source tree.

d276a604bf linux-user: elfload: Provide default for elf_check_arch
For many arch's this macro is defined as the predicatable behaviour
of checking the argument for eqaulity against ELF_ARCH. Provide a
default define as such, so only archs with special handling (usually
allowing multiple EM values) need to provide a def.

Arches that do any of:

1: provide this def exactly the same way as the new default
        (alpha, x86_64)
2: check against ELF_MACHINE while defining ELF_ARCH == ELF_MACHINE
        (arm, aarch64)
3: check against EM_FOO directly while defining ELF_ARCH == EM_FOO
        (unicore32, sparc32, ppc32, mips, openrisc, sh4, cris, m86k)

have their elf_check_arch removed as the default will provide the
correct behaviour.

ba10f729f1 get_maintainer.pl: \C is deprecated
"Match a single C-language char (octet) even if that is part of a larger
UTF-8 character.  Thus it breaks up characters into their UTF-8 bytes,

57f5462929 Makefile: fix build when VPATH is outside GIT tree
Steve Ellcey / Leon Alrae reported that QEMU fails to build when
the VPATH directory is outside of the GIT tree, and the system
emulators & tools build is disabled. eg

   cd ..
   mkdir build
   cd build
   ../qemu/configure --disable-system --disable-tools
   make
   (...)
   make[1]: *** No rule to make target `../qom/object.o', needed by `qemu-aarch64'. Stop.
   make: *** [subdir-aarch64-linux-user] Error 2

The problem is due to the fact that some sub directory deps
were listed against SOFTMMU_SUBDIR_RULES instead of SUBDIR_RULES,
so were only processed for system emulators, not user emalutors.
