57e4541190 prune-trace: do not sort ECs for sampling
Sorting is too costly for large data sets, and not worth the
sampling-process speedup.

b2b53380f4 prune-trace: add switch to disable sample weighting
In the sampling step, the --no-weighting switch disables the
equivalence-class weighting by using a weight of one instead of the
equivalence-class size.  This is usually not a good idea, and should
only be used for demonstration purposes, or if the fault model
requires weight-less sampling.

a1e3b31cd5 prune-trace: sample from known results
The --use-known-results switch simulates sampling (with fault
expansion, FESamplingPruner) by reusing results from a previous
campaign covering the full fault space (that used the "basic" pruner).
The pruner only creates entries in the "fspgroup" table that refer to
already existing pilots and corresponding results.

This switch is not for normal Fail* use, but only for experimenting
with the FESamplingPruner.

d9028e9d70 CMake: Fail* version number handling fixed
The project version number is now not user-editable anymore, and
custom values get overwritten by force.  Without this change,
CMakeCache.txt stays at the version number it was first instantiated
from.

a00c4d9a69 util/DwarfReader: plug file-descriptor leaks
This change fixes several file-descriptor leaks in the DwarfReader
implementation.  The patch is taken from Richard Hellwig's not yet
merged change I161f626d12ca7f2b7b9d13ba9cbc254eb55692f1.  I did not
apply any white-space cleanups to prevent conflicts when Richard's
change will be merged later.

d68ea990ca sal: catch listener removal corner case
This change makes sure an active but not-yet fired listener does not fire
anymore if it gets removed.  In this case, the listener already has an
invalid index, but still needs to be copied to the delete list.

This issue has not been observed in the wild, and is unlikely to have
caused real problems in the past.

c4d44aeb0c sal: fix watch/breakpoint perf implementation
This commit changes the entities in a ResultSet from listener indexes
(into ListenerManagers m_BufferList) to BaseListener pointers, as
ListenerManager::makeActive(BaseListener*) (called from
FastBreakpoints/Watchpoints.ah) may invalidate indexes temporarily
stored in a ResultSet.  The issue occurs when multiple breakpoints
(watchpoints) fire at the same time, and one added more recently than
the others occupies the largest index position in m_BufferList.

Although this issue is extremely rare and was only observed in a few
corner cases up to now, it may have falsified results in the past.

722715c01f fail-cleanup-db.sh: cleanup unused DB entries
This script removes dangling rows from the database, for example
'trace' entries with a variant_id not mentioned in the 'variants'
table, or result rows referencing a nonexistent 'fsppilot' entry.
IOW, this script enforces referential integrity as it would be
maintained by foreign key constraints (that can only be used with
InnoDB tables).

e83e87ecc7 DwarfReader: fixed linetable mapping
This change alters/corrects DwarfReader's way of determining the size of
linetable entries (i.e. their "range size"); the interface (e.g. to
ElfReader) stays the same. Prior to this, it was assumed that static
instructions within "the linetable" were sorted in ascending order. This
assumption turned out to be false, as every compilation unit's  header has
its own linetable and the compilation unit headers are not sorted by their
static instructions.
Furthermore this change implements normalization of file names.

36d9e77c96 import-trace: extend sanity checks to time1/2
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.
