This one omitted mappings to the first static instruction belonging to a
high-level source-code line.

Using "$x .= $y" instead of "$x = $x . $y" is actually an extreme
speedup for long $x. I had no idea PHP's "compiler" was that bad and
doesn't optimize this.

The dbg_methods, dbg_variables and dbg_stacktrace tables are not
needed by the current VisualFAIL implementation.

Luckily this didn't work as advertised, as the global connection
variable wasn't imported into the functions' scopes.

Up to now, the sanity checks only tested equivalence classes
determined by dynamic instructions (instr1/instr2), although the
actual timing boundaries (time1/time2) have been the really relevant
information for quite some time now. This change extends the checks
to time1/time2.

The sanity check testing whether the fault space is rectangular is
unnecessarily slow, as it joins the "trace" table without any reason,
and includes all variants instead of the currently imported one.

For the objdump retrieval, the result_VEZS.. was used. Instead of that
hardcoded string, the parameter should be used instead.

This change implements the following:
-DwarfReader now exports the address range of linetable-entries instead of
only the first address
-ElfImporter saves this range alongside the mapping
Change-Id: I7fe6361178f761a8f605a44bb0183c56a236cc95
This change alters DwarfReader and import-trace's ElfImporter so that they use
unsigned int for static address and line numbers instead of signed int.

Up to now, source code lines and mappings from static instruction
addresses to lines could be linked to the wrong file if
dbg_filename.path contained duplicates. This is unfortunately the
normal case when importing multiple variants of the same program into
the database.

This change removes the "--debug" parameter, which previously imported the
mapping of source code lines to static instructions into the database. This
mapping is useless by itself (i.e. without "--sources"), which is why its
code was refactored into the code handling "--sources".

This change makes all C++-based tools in tools/ abort when they
encounter an unknown commandline parameter (both option or
non-option). This has already caused some confusion, as in some cases
unexpected behaviour can be the result. For example, "prune-trace -t
mytrace.tc -d database" up to now ignored the "-t" parameter, took
"mytrace.tc" as the first non-option parameter (and ignored it); as no
option parameter may follow the non-option parameters, all other
options were ignored as well.

By using the AliasedRegistry, "prune-trace --help" (and
"prune-trace -p '?'") now lists all available Pruners to the user.

With this change, prune-trace checks for existing fsppilot/fspgroup
entries for each variant to be pruned, and skips the variant in this
case. This safety measure can be switched off with --overwrite.

The FESamplingPruner implements the fault-expansion variance reduction
technique (FE-VRT) as described in: Smith, D. Todd and Johnson, Barry W. and
Andrianos, Nikos and Profeta, III, Joseph A., "A variance-reduction technique
via fault-expansion for fault-coverage estimation" (1997), 366--374.

If no --variant / --benchmark is specified, it's more reasonable to
prune or run *all* variants/benchmarks (using the wildcard "%")
instead of defaulting to "none"/"none". The trivial case with only
one single variant/benchmark (which may still be "none"/"none" if
import-trace's default is used) is still covered by this new default
behavior.

This change moves prune-trace's --variants-exclude / --benchmarks-exclude
capabilities to Database::get_variants() to make it available to all users.
Change-Id: Icbc6bb1a3ae7c846d2de40b881f47a9cc1ed7bbf
Otherwise it's not possible to keep a "basic" and a "sampling" pruned
version of one variant in the same database.
