As the first cmd.parse() call was already checked before, parsing a
second time should never fail. Nevertheless, we can look at the
return value without much effort. Found by Coverity Scan, CID 25494.

To use the new clang-based AspectC++ (ac++ >1.2), Fail* must be built
with -D__NO_MATH_INLINES (or --c_compiler clang++).

Analogous to the FESamplingPruner, 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.
The --no-weighting switch was introduced with an earlier commit, but
did not have an effect until now.

In bash, ${parameter:=word} assigns the default value. In our case,
${parameter:-word} (the whole expression has a default value, but it's
not assigned) suffices.

These IDs don't make sense by themselves but only after a lookup in the

The --incremental switch allows to add more samples if the resulting
confidence intervals are not satisfactory yet.

The SamplingPruner implements "normal" sampling with equivalence-class
reuse. Unlike the FESamplingPruner, the SamplingPruner implements
uniform fault-space sampling that counts multiple hits of an
equivalence class.
This change modifies the database schema, more specifically it adds
the "weight" column to the fspgroup table. Update existing databases
with this query:
ALTER TABLE fspgroup ADD COLUMN weight INT UNSIGNED;

SumTree::get now non-intrusively picks an element and returns a
reference to it, SumTree::remove removes and returns a copy. The
former is needed for sampling with replacement.

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.

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.

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.

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.

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.

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).
