Buffered bulk mode is intended for bulk *input* endpoints, where the data is
of a streaming nature (not part of a command-response protocol). These
endpoints' input buffer may overflow if data is not read quickly enough.
So in buffered bulk mode the usb-host takes care of the submitting and
re-submitting of bulk transfers.

Buffered bulk mode is necessary for reliable operation with the bulk in
endpoints of usb to serial convertors. Unfortunatelty buffered bulk input
mode will only work with certain devices, therefor this patch also adds a
usb-id table to enable it for devices which need it, while leaving the
bulk ep handling for other devices unmodified.

Note that the bumping of the required usbredir from 0.5.3 to 0.6 does
not mean that we will now need a newer usbredir release then qemu-1.3,
.pc files reporting 0.5.3 have only ever existed in usbredir builds directly
from git, so qemu-1.3 needs the 0.6 release too.

Default to 'cc' as our compiler, rather than 'gcc'. We used to have
to insist on gcc when we still kept the CPU env in a fixed global
register, but this is no longer necessary and we will now compile OK
on clang as well as gcc.  Using 'cc' should generally result in us
using the most standard and maintained system compiler for the
platform.  (For instance on newer MacOS X 'gcc' exists but is an
elderly compiler provided mostly for legacy reasons, and 'cc'
(which is clang) is definitely the better choice.) On Linux there
will generally be no user-visible change since cc will be gcc.

This changeover necessitates a slight reworking of how we set the
'cc' variable, because GNU cross toolchains generally provide a
'${cross_prefix}gcc' but not a '${cross_prefix}cc'.

gcc will silently accept unrecognized -Wno-wombat warning suppression
options (it only mentions them if it has to print a compiler warning
for some other reason). Since we already run a check for whether gcc
recognizes the warning options we use, we can easily make this use
the positive sense of the option when checking for support for the
suppression option. This doesn't have any effect except that it avoids
gcc emitting extra messages about unrecognized command line options
when it is printing other warning messages.

Disable clang's initializer-overrides warnings, as QEMU makes significant
use of the pattern of initializing an array with a range-based default
entry like
    [0 ... 0x1ff] = { GPIO_NONE, 0 }
followed by specific entries which override that default, and clang
would otherwise warn "initializer overrides prior initialization of
this subobject" when it encountered the specific entry.
