Since commit c142818, DatabaseCampaignMessage.proto is generated into
the binary directory, which must be announced to the protobuf
compiler.

Enabling both CONFIG_FAST_BREAKPOINTS / CONFIG_FAST_WATCHPOINTS and
CONFIG_EVENT_BREAKPOINTS / CONFIG_EVENT_BREAKPOINTS_RANGE /
CONFIG_EVENT_MEMREAD / CONFIG_EVENT_MEMWRITE led to an (unnecessary)
include cycle.

This change allows to use the generic-tracing experiment with a
manually specified start/stop address. This is necessary to use it
with more complex systems that aren't booted from a single ELF file,
such as Fiasco.OC.

BochsController::getTimerTicksPerSecond() only works reliably when the
simulation is already running (e.g., after a restore()). This broke
timeout conditions for the very first experiment in a FailBochs instance.

This change makes the DatabaseCampaign load all pilot_ids from the result
table in memory instead of LEFT JOINing them for each variant. This vastly
improves campaign speed (possibly making commit 5567c59 superfluous) at the
cost of slightly increased startup time for half-completed (large)
campaigns.
By exploiting the generally continuous nature of pilot IDs and using a
boost::icl::interval_map, the additional memory requirements are
insignificant.

When no variants matching the command line parameters were found, the
campaign printed an uninitialized sent_pilots count.

The fix for tools/convert-trace/Gem5Converter.cc repairs a real issue

This crippled version of the weather-monitor experiment is not needed
anymore, as gem5's restore() works now.

This change implements a generic registry in order to clean up import-trace's
code - it's possible (and reasonable) to use the registry for pruners as well.
Importer now extends AliasedRegisterable; all importers have been adapted
to suit the interface/abstract methods.
Each AliasedRegisterable should have at least one alias (the class' name
is a sensible choice) but can have several. The first specified alias is
the class' prime alias which can be used e.g. to list all registered objects.

The libiberty headers moved from /usr/include (and a part of binutils-dev)
to /usr/include/libiberty (libiberty-dev) between Ubuntu 13.10 and 14.04,
which made a proper cmake search module necessary. Searching still
continues working well on Debian 7.

This change adds an optional command line argument "--database-option-file",

Somehow, while iterating symbols in a section, it can happen that the last
symbol start address is equal to the section size, which means it is beyond
the section end.
In this case the LLVM getInstruction() method does not return a failure, but a
zero-size instruction, resulting in an infinite loop.
Now, if beyond section limits, the iteration is aborted.
Additionally, an assertion checks for disassembled zero-size instructions.

As the eCos kernel tests do not sufficiently check for failures, a
(compared to the golden run) measurably *reduced* simulation time can be
used as an indication for SDC.

Instead of hardcoded -lelf/-ldwarf use cmake modules FindLibElf/-Dwarf
and link the found libraries accordingly. This enables the user to have those
libs in arbitrary locations and link them from there.

With this change, x86 special-purpose registers (e.g., EFLAGS) get the
same register ID in both 32 bit and 64 bit configurations.
Change-Id: I69db9397481414f99ca05ecb0ea9dc8ab7d989c9
This bug mapped EFLAGS to the same Fail* register ID as R9 on x86_64. This
probably has not had consequences yet, as most FailBochs users use 32-bit
code.

There are instruction in the real world, that seem to read more than 8 bytes.
Therefore we cap the accesses memory to 8 and don't abort with an assertion.

Internal LLVM register IDs can and did change between LLVM versions.
These magic integers are replaced by iterating over all LLVM registers
and mapping them to FAIL* registers by name.
As this iteration requires a LLVM object created from a binary, a static
convenience function is added to LLVMtoFailTranslator which creates a
translator given the binary filename. Building this functionality inside
libfail-llvmdisassembler prevents experiments from needing to add LLVM
includes and library definitions.

CMake does not support linker groups, which were used to "automatically"
fix circular dependencies between different static FAIL* libraries and
the ordering of dynamic external libraries broke linking.
CMake can however correctly invoke the linker if dependencies are decribed
correctly (even if circular). This required changing all add_dependencies
calls between libraries to target_link_libraries (which creates a link-time
dependency) and linking all experiments to fail-sal.

If the queue for outbound jobs is not unlimited, experiment rows are fetched
from the DB server continuously as experiments finish. When this takes too
long the connection to the DB server can be lost. The code did not check for
a mysql_error and assumed the result set was fetched completely, thus skipping
a potentially large amount of experiments (in our case only ~20000 of 400000+
experiments were run).
This change adds checks to determine if the result fetch loop was finished due
to an error and checks the sent pilot count to the unfinished experiment count.
Additionally, the mysql result object is correctly freed.
The underlying problem of MySQL connection loss can hopefully be prevented by
increasing timeouts in the MySQL config as described in doc/how-to-build.txt.
To prevent the problem from occurring when this is forgotten, this change
reverts the default job queue length to be unlimited (SERVER_OUT_QUEUE_SIZE=0),
at the cost of increased memory usage.

The database queries to fetch all unfinished experiments were broken.
The server tried to insert all finished pilot_ids into the temporary
result_ids table and then discard all experiments which have the correct
(finished) count of IDs in this table. This cannot work as the pilot_id
is the only column of result_ids and must be a unique primary key.
As a fix, the count of results is stored as a second field in result_ids
and the result table is now joined against result_ids to check this field.

When socket(2), setsockopt(2), bind(2), listen(2), or accept(2) return an
unexpected error status, it is usually not a good idea to let the campaign
continue. This is especially a problem as the perror(3) message gets lost
in normal campaign output and may be missed by the user.
