Python3 versions less than 3.7 have very unhelpful handling
of the C locale where they assume data is 7-bit only. This
violates POSIX which requires the C locale to be 8-bit clean.
Python3 >= 3.7 now assumes that the C locale is always UTF-8.
Set env variables to force LC_CTYPE to en_US.UTF-8 so that
we get UTF-8 handling on all python versions. Note we do
not use C.UTF-8 since not all C libraries support that.

A common operation in qemu_domain_address is comparing a
virPCIDeviceAddress and assigning domain, bus, slot and function
to a specific value. The former can be done with the existing
virPCIDeviceAddressEqual() helper, as long as we provide
a virPCIDeviceAddress to compare it to.
The later can be done by direct assignment of the now existing
virPCIDeviceAddress struct. The defined values of domain, bus,
slot and function will be assigned to info->addr.pci, the other
values are zeroed (which happens to be their default values too).
It's also worth noticing that all these assignments are being
conditioned by virDeviceInfoPCIAddressIsPresent() calls, thus it's
sensible to discard any non-zero values that might happen to exist
in @cont->info.addr, if we settled beforehand that @cont->info.addr
is not present or bogus.

When the bridge re-attach handling was moved out of the network driver
and into the hypervisor driver (commit b806a60e) as a part of the
refactor to split the network driver into a separate daemon, the check
was accidentally changed to only check for type='bridge'. The check for
type in this case needs to check for type='network' as well.
(at the time we thought that the two types could be conflated for
interface actual type, but this turned out to be too problematic to
do).

The colors are not based on the semantics of the message but rather
on the message itself. This means that the default human-perceived
semantics (red = bad, green = good) don't really apply and spotting a
color does not mean anythting.
This is amplified by the sheer amount of output which configure produces
and the fact that some of the messages have negative semantics or
additional output.
In case of any problem the user will have to go through everything
anyways as spotting a red or yellow line has 0 information value.
Here are a few examples:
1) some 'no' messages are not a problem:
checking minix/config.h presence... no
2) some 'no' messages are actually positive:
checking for special C compiler options needed for large files... no
3) in some cases a 'yes' would mean that something is broken or needs
workaround
checking whether stat file-mode macros are broken... no
checking whether wint_t is too small... no
checking whether stdint.h predates C++11... no
checking whether the inttypes.h PRIxNN macros are broken... no
checking whether clang gives bogus warnings for -Wdouble-promotion... no
checking whether gettimeofday clobbers localtime buffer... no
4) due to string match based colors extra text makes messages yellow
checking for a traditional french locale... none
checking for working nanosleep... no (mishandles large arguments)
checking for library containing gethostbyname... none required
checking whether mbrtowc handles incomplete characters... (cached) guessing yes
5) in some cases the yes/no is very context dependant
checking whether pthread_rwlock_rdlock prefers a writer to a reader... no
checking whether this build is done by a static analysis tool... no
6) detected paths to binaries and libs are yellow despite being present
checking for objdump... objdump
checking for atomic ops implementation... gcc
As of the reasons above I don't think the colorization of the configure
output helps users or developers to debug the build process and
thus is not worth the extra code or output clutter.
This reverts commit c98174ce08.

The colorization based on the string itself makes little to no sense as
the semantic meaning of the color (red = bad, green = good) is not
extracted from the semantics of the message:
1) If there is some additional string a 'yes' is marked yellow:
configure: driver_modules: yes (CFLAGS='' LIBS='-ldl')
2) In some cases a 'no' is actually good:
configure: hal: no
3) Few good/recommended configuration options are still yellow:
configure: QEMU: qemu:qemu
while using 'root:root' would still be yellow.
4) fields dumping config (e.g. the warning flags line) is a giant blob
of colored text which makes little sense
configure: Warning Flags: -fno-common -W -Wabsolute-value
-Waddress -Waddress-of-packed-member -Waggressive-loop-optimizations
-Wall -Wattribute-warning -Wattributes -Wbad-function-cast
-Wbool-compare -Wbool-operation -Wbuiltin-declaration-mismatch

-Wdiscarded-array-qualifiers -Wdiscarded-qualifiers -Wdiv-by-zero
-Wdouble-promotion -Wduplicated-cond -Wduplicate-decl-speci ...
In addition if the idea is to switch to a more usable build system it
does not make sense to clutter the current one with more code.
