This patchset introduces the idef-parser for target/hexagon.
It's the sixth iteration of the patchset and includes fixes suggested in
previous iterations.
`idef-parser` is a build-time tool built using flex and bison. Its aim
is to generate a large part of the tiny code generator frontend for
Hexagon. The prototype of idef-parser has been presented at KVM Forum
2019 ("QEMU-Hexagon: Automatic Translation of the ISA Manual Pseudcode
to Tiny Code Instructions"):

`target/hexagon/idef-parser/README.rst` provides an overview of the
parser and its inner working.
A couple of notes:
* Among other things, this commit ensures the signedness is always
properly propagated and that memory safety tools (valgrind and various
sanitizers) report no issues on the parser.
* We now also indent the generated C code using `indent`, if availble.
This has no run-time effect, it's just to ease debugging.
* These commits build successfully on the CI (including using clang),
with some exceptions.
The build on the CI fails for the cross-i386-* jobs. This seems to be
due to the fact that, despite we specified glib as a native
dependency, meson still chooses the i386 bit version of the library,
as opposed to the x86-64.
We also introduced a commit to make sure containers produced by the
developer Docker registry (as opposed to the official one) is
used. Otherwise, the changes we made to the containers would not
take effect.
However, as Daniel pointed out, our solution is an hack.
Since this is a problem only for developers when introducing new
dependencies for the containers, we might consider not merging the
last patch at all. But it's required in order to get some success in
testing on the CI it required.
Also, building debian-hexagon-cross still fails since it's not built
by the CI by default.
Help on these matters is appreciated.
