Backport the CTF-IR interface

debug info: Call register_event_debug_infos for all events

The register_event_debug_infos function is responsible for setting the
debug_info_src field of the struct definition_integer representing the
"ip" context field.  This pointer is used later to print the
source and binary location of the tracepoint.

Currently, it's not called for the events that have a special meaning
for the debug info analysis (statedump start, dlopen, bin_info, etc).
This means that for these events, the debug_info_src pointer keeps the
value of the previous event from that stream (since the ip field is in
stream event context, there is one instance per stream), which leads to
wrong information and/or crash.  A crash can happen when the debug info
structures are cleared because a statedump start is encountered.
debug_info_src becomes a stale pointer and babeltrace tries to print a
string in free memory.

The fix is to call register_event_debug_infos for all events, which will
always set debug_info_src properly.  The events used to do the debug
info analysis are still regular events and have their own location
information.

The trace in bug #1018 shows a crash caused by this issue.

Here's an example of wrong info from the same trace:

... lttng_ust_statedump:bin_info: { cpu_id = 1 }, { vpid = 28991, ip = 0x7FD26665657D, debug_info = { bin = "libX11.so.6.3.0+0x213fa" } }, ...
... lttng_ust_statedump:build_id: { cpu_id = 1 }, { vpid = 28991, ip = 0x7FD266656656, debug_info = { bin = "libX11.so.6.3.0+0x213fa" } }, ...

We can see that the ip values are different, but the debug info refers
to the same location, which is impossible.  Here's the result with this
patch applied.

... lttng_ust_statedump:bin_info: { cpu_id = 1 }, { vpid = 28991, ip = 0x7FD26665657D, debug_info = { bin = "liblttng-ust.so.0.0.0+0x3557d", func = "trace_bin_info_cb+0xfa" } }, ...
... lttng_ust_statedump:build_id: { cpu_id = 1 }, { vpid = 28991, ip = 0x7FD266656656, debug_info = { bin = "liblttng-ust.so.0.0.0+0x35656", func = "trace_build_id_cb+0xbc" } }, ...

which seems more reasonnable.

configure: fix uuid support detection on static build

This change adds uuid detection using pkg-config helper before falling
back on the standard AC_CHECK_LIB detection for platforms missing
pkg-config.

AC_CHECK_LIB function achieves its test by trying to link against the
requested library, without taking care of its dependency
requirements/flags that may differ between different targets.
Therefore, in case of static build, it can fail on the uuid detection
like [1], because the uuid's dependency flags (regarding gettext) are
missing.

Instead, using pkg-config to do the check will take care of getting and
setting all required flags.

This issue [1] has been triggered on Buildroot farms.

The expression "min_value = -((int64_t)1 << (size - 1))"

((1ULL << 63) > LONG_MAX).

Note that larger sizes are unsupported and checked for in the setter.

Signed overflows result in undefined behaviour and llvm takes
advantage of this to optimize away the range check

"if (value < min_value || value > max_value) {"

Surprisingly, this was not catched by GCC, Coverity, scan-build or

The fix consists in computing both bounds using an unsigned long long
type and, in the case of the lower bound, negating it (resulting in a

Set the minimal version of elfutils to 0.154

elfutils 0.154 is required since it is the first release to
include commit 5479725 (dwarf_highpc: Handle DW_AT_high_pc being
a constant offset from DW_AT_low_pc).

This is fix is required to read DwARF information produced by
"modern" (post-2012) GCCs which make use of this DWARF4
capability when generating position independant code. The binaries
provided as part of the test suite make use of this feature. Hence,
tests will fail with older elfutils versions.
