In order to allow overriding flags that are set by configure, we have to
append them instead of prepending as it is done so far.

In order to build the multiboot option rom, we need a Makefile and a tool
to sign the rom with.
Both are provided by this patch and mostly taken from the extboot source,
written by Anthony Liguori.
Once built, the resulting binary gets copied to pc-bios automatically.
Building also occurs automatically when on an x86 host.

Not every distro provides libcurses anymore, at least OpenSUSE, and at
least under a standard library search path. So try to link against
standard ncurses first and then fall back to legacy curses.

The glibc function for utimensat glibc returns -EINVAL when the path is null
which is a different behaviour with the syscall.
path can be null because internally the glibc is using utimensat with
path null when implmenting futimens. If path is null, call futimes
instead.
don't try to copy timespec from user if is NULL.

Currently Qemu can read from posix I/O and NBD. This patch adds a
third protocol to the game: HTTP.
In certain situations it can be useful to access HTTP data directly,
for example if you want to try out an http provided OS image, but
don't know if you want to download it yet.
Using this patch you can now try it on on the fly. Just use it like:
qemu -cdrom http://host/path/my.iso

--disable-gfx-check predates VNC server support. It made sense back then
because the only thing you could do without SDL was use -nographic mode or
similar tricks. Since this is a very advanced mode of operation, gfx-check
provided a good safety net for casual users.
A casual user is very likely to use VNC to interact with a guest. In fact, it's
often frustrating to install QEMU on a server and have to specify
disable-gfx-check when you only want to use VNC.
This patch eliminates disable-gfx-check and makes SDL behave like every other
optional dependency. If SDL is not available, instead of failing ungracefully
if no special options are specified, we default to -vnc localhost:0,to=99.
When we do default to VNC, we also print a message to tell the user that we've
done this include which port we're currently listening on.

The only target dependency for most hardware is sizeof(target_phys_addr_t).
Build these files into a convenience library, and use that instead of
building for every target.
Remove and poison various target specific macros to avoid bogus target
dependencies creeping back in.
Big/Little endian is not handled because devices should not know or care
about this to start with.

This is no user-flippable switch, and no arch makes use of disabling
gdbstub support. So it's pointless to keep the related #ifdefs and
configure hunks around - and risking breakages like 711c410fdd again.
