1 Yes we do support DESTDIR.
2 From packaging scripts, use something like this:
make install DESTDIR=$RPM_BUILD_ROOT PREFIX=/usr
(v2: add PREFIX, install to /usr/local not /usr by default)

$(E) " ACTION " files
We maintain specific whitespace around ACTION so different ones
are aligned nicely. Fix two places that were not aligned to the rest.

$(E) is used for 'silent make' to inform about what is going on
when we are not printing actual commands being executed, and do
nothing in case of 'verbose make (i.e. make V=1).
For 'make help' we want to output the text regardless of whether
'silent make' is enabled or not.

This is lots-of-bug-fixes release -- many new people started playing
with criu and reported a lot of issues with it.
Other than this, we have several new features. First of all it's C/R
of netlink sockets C/R (required for Fedora container dump) and pending
signals.
Next, we've changed the format of memory dumps. This allowed us to
implement so called page server, that allows to send memory dumps
directly on another box w/o intermediate dump file. Also this new
format made it possible to implement the (not yet final) --snapshot
option, that demonstrates the work of user memory changes tracker
in the kernel.

"Tools" in the context of a binary name doesn't make any sense,
because every binary is a tool (lstool, dftool), plus it's one
tool.
So let's rename the beast to criu, which is short, pretty unique
and coincides with the name of the project.
Backward-compatible symlink is added for the sake of tests,
we can fix them later and remove the link.
Packagers beware: our binary is no longer crtools but criu.

1 The comment before MAKEFLAGS assignment (see commit 25e8cb5) talks
about -r (and possibly -R) flags and has nothing to do with
--no-print-directory. Let's remove the last option to not confuse
a reader.
2 The --no-print-directory flag to build and build-crtools shorthands
is redundant, because scripts/Makefile.build has it already. Remove.

This is the first release, that actually doesn't require a custom
kernel in order to make all the tool features to work. Just take
the v3.8 (with proper config) and that's it :)
Another coolness about this release is the ARM port. In this case,
however, one does require a custom kernel, since the kcmp system
call is not wired into the ARM table in the upstream kernel :(
What else? Quite a lot, actually:
* C/R ability of a LOT of new stuff
* Remote syscall execution
* Deprecation of --namespace option
* Build system rework
* Ability to collect gcov info

Some of ours headers (such as syscall.h) are
clashes with system headers names. So we need
to be sure that the headers we include as
| #include "something.h"
being searched in known place. In particular on
some machines it it already produced problems.
This btw revealved a problem in cr-dump.c -- we've
had #include <parasite.h> there. Fix it.

This is a bit tricky since the build infrastructure
we're switching to is targeted to per-directory targets
if simplified Makefiles are used.
So I did the following
- move rules to compile general sources to Makefile.crtools
- main Makefiles now simply calls for scritps/Makefile.build
help to generate built-in.o target
Also note that we clean up suffixes for implicit rules with
.SUFFIXES:
this is done on purpose to eliminate any possible side effect
in future -- all rules _must_ be described explicitly.
Because of implicit rules used in zdtm building procedure
I can't use of stict makefile mode and add
MAKEFLAGS := -r
to the top of the general Makefile. This should be done
one day latter (if ever).

We collect all file locks to a golbal list, so we can use them easily
in dump_one_task. For optimizaton, we only collect file locks hold by

Thanks to the ptrace-seize machanism, we can aviod the blocked file lock
issue, makes the work simpler.
Right now, the check handles only one situation:
-- Dumping tasks with file locks hold without the -l option.
This covers for the most part. But we still need some more work to make
it perfect robust in the future.

This patch add ability to test /proc/cpuinfo data
we're interested in at the moment.
The code provides the following functionality
- cpu_init, to parse cpuinfo and check if the
host cpu we're running on is suitable enough
for FPU checkpoint/restore. If FPU present then
there must be at least fxsave capability present
- cpu_set_feature/cpu_has_feature helpers which
provides to test certain bits and set them where
needed (we need to set bits when parse cpuinfo)
Note, we reserve space for all cpuinfo bits known
by the kernel at moment, while use only three FPU
related bits for a while. This is done because we might
need to use or find out other features in future.
After all it's just 40 bytes of memory needed to keep
all possible bits.
