Packages which inherit fontcache.bbclass call postinstall script
update_font_cache. And in update_font_cache, it calls ${bindir}/fc-cache
by qemuwrapper. When multilib is enabled, both packages foo and lib32-foo
will call ${bindir}/fc-cache and one of them will fail to run obviously.
Duplicate install file fc-cache to ${libexecdir} with ${MLPREFIX} and
call proper fc-cache in update_font_cache.

Previously only one global variant of the script was created,
which caused numerous issues:
1) multilib was not properly supported due to multilib variants each
needing their own version of the qemu binary and library paths to be set
2) nativesdk was not properly supported for the same reason
This patch also moves setting LD_LIBRARY_PATH directly into the
recipe, as passing it down from other recipes did not work when
said recipes were allarch, and adjusts calls to qemuwrapper from
postinst-intercepts, so that its correct variant is selected.
Also, the various qemu fallbacks in qemuwrapper script are all removed,
as they are no longer necessary.

If a postinst has a problem (say, qemu crashes) and set -e isn't in operation,
the only mention of the problem is a single line in the rootfs log that doesn't
trigger any warnings.

By default fc-cache will scan both system and user directories, which means it
attempts to scan $HOME/.fonts. As this is the build host's idea of $HOME this
generally doesn't exist, and causes fc-cache to exit with a failure.
Solve this by passing --system-only so that fc-cache will only scan system
directories, as is appropriate for a rootfs-time invocation.

* this can be useful for passing extra parameters, pass
-v by default to see what's going on in do_rootfs
* we need to use this for extra parameter we implemented
in fontconfig:
--ignore-mtime always use cache file regardless of font directory mtime
because the checksum of fontcache generated in do_rootfs
doesn't match with /usr/share/fonts directory as seen on
target device causing fontconfig to re-create the cache
when fontconfig is used for first time or worse create
new cache in every user's home directory when /usr/
filesystem is read only and cache cannot be updated.
Running FC_DEBUG=16 fc-cache -v on such device shows:
FcCacheTimeValid dir "/usr/share/fonts" cache checksum 1441207803 dir checksum 1441206149
* my guess is that the checksum is different, because pseudo
(which is unloaded when running qemuwrapper) or because some
influence of running the rootfs under qemu.

The file ownership of the cache files in /var/cache/fontconfig needs to
be set to root:root otherwise it inherits the user and group id of the
build user.

The redirection was necessary with the old bash code because the log
checking routine was searching for error strings in the log and abort
the build in case failures occured. With the new python code,
redirecting the intercept stderr is no longer necessary. This also makes
the intercept hooks easier to debug.

Postinstalls that use qemu are throwing a segmentation fault when
building for qemux86-64 on a 64bit host (it might also happen for
qemux86 if building on a 32bit host but I didn't test). It looks like
qemu looks for ld.so.cache which is not found because it is generated
after rootfs_(rpm|ipk|deb)_do_rootfs is called and then it tries to load
libraries from the default paths (which are the host's). In order to
avoid this, pass the LD_LIBRARY_PATH explicitly to the target's dynamic
loader.

The intercept scripts fail to run on 32 bit hosts. Apparently, the
current approach worked on 64 bit hosts due to the larger virtual address
space (probably). On 32 bit hosts, however, calling the target binary like:
qemu-arm ld-linux.so --library-path /lib:/usr/lib arm_binary
fails with:
arm_binary: error while loading shared libraries: arm_binary: failed to
map segment from shared object: Operation not permitted
When run like this, qemu-arm fails to map the arm_binary executable in
memory because it's hitting the lower limit of
/proc/sys/vm/mmap_min_addr. That's because it loads the
ld-linux.so binary successfully, taking into account mmap_min_addr, runs
it, and then ld-linux.so will map the arm_binary at a fixed address but this
will fail because it is below mmap_min_addr. The qemu's guest base probing,
apparently, doesn't work fine when a program runs inside other.
One way around this would be to set mmap_min_addr to 0 (on recent
distributions is set to 65536 to avoid "kernel NULL pointer dereference"
defects) but this approach is not safe.
The other way is to call the binary directly but providing qemu with a
prefix (-L option) in order to find the elf interpreter correctly. This
way, both the target binary and dynamic loader are mapped into memory
under qemu's control and, only after, the dynamic loader is started.

The scripts/postinst-intercepts will contain all postinstall hooks that
we need to run after all packages have been installed.
If one wants to install such a postinst hook, all it needs to do is put
the hook in this directory and, from the package postinstall scriptlet,
call:
postinst_intercept <hook_name> <package_name> <var1=...> ...
This will, practically, add the package_name in the list of packages
that need the hook to run and, also, set any variables that would be
needed in the hook. For example, variables like ${libdir}, ${bindir},
etc. that might depend on distribution can be passed on to the script in
this way.
