If the user enabled multiple experiments, it does not make sense to
execute them concurrently. Therefore, we now only register all enabled
experiments and choose one experiment on fail-client startup. For this
selection, the user can either set the FAIL_EXPERIMENT environment
variable or invoke the tool with a specific argv[0]. For the
bin/-folder, we create symlinks for this mechanism.
With this change, the generic-tracing and generic-experiment can be
compiled into the same executable and we could distribute a "standard"
version of FAIL*.
The previous path google::protobuf::Message::Reflection was deprecated
in 2008 (779f61c6a3ce02a119e28e802f229e61b69b9046), and we only used
it here. With newer versions of proto-c, this breaks the build.
This is an API breaking change. Nevertheless, help text and
command-line parser were out of sync and the variant of the help-text
does make much more sense.
Symbol type FUNC (STT_FUNC, "code object") seems not to suffice when parts
of the disassembled binary come from assembler source files. We try to
disassemble STT_NOTYPE (symbol type "unspecified") as well now.

Especially for dynamically linked ELF binaries (such as those in the
testing/ subdirectory), symbols with a start address outside the .text
section may exist. This change skips any symbol that is not fully within
this section (and assigns a reasonable size to a zero-sized last symbol
within the symbol table), and turns green all Capstone-related test cases.

This version check could (and probably should) also be done in the cmake
scripts. However, this check in CapstoneDisassembler.cpp catches another
failure mode: When a cmake script is missing a include_directories()
directive pointing to capstone.h -- resulting in a missing -I parameter to
gcc -- accidentally a system-wide 3.x capstone.h may get #included,
providing the wrong definitions and prototypes to some translation units.

The switch to MariaDB Connector/C 3.0 involves some subtle API
changes, including the fact that "~" is not expanded to the user's
home directory anymore. This change expands the HOME environment
variable within our code base.

Some libraries, e.g. protobuf, depend on C++11 now. As they are
(indirectly) included in some .ah aspect headers, everything has to be
compiled with C++11 enabled now.
This change switches to C++14 globally.

Due to a typo (cast to regwidth_t instead of regdata_t), accesses to
register content beyond an offset of 32 bits via
LLVMtoFailTranslator::reginfo_t did not work correctly. Additionally, this
change fixes constructing reginfo_t with a bit width >= 64 (e.g. the whole
RAX register).

Using switch/case instead of an if cascade is more readable and has a
better chance to be optimized.

The "--[Server] No workload, come again..." appears every time a
larger job set is loaded from the database, once for every client that
knocks. This isn't helpful and scrolls out relevant information,
hence I'm removing it for now.

The -p parameter is already being used by several campaign servers for
the prune method to restrict to (which was broken in commit
6c120004e), hence allow only --port to choose a different server TCP
port at runtime.

std::chrono::system_clock is not monotonic, instead use

If the JobServer is provided a total number of experiments by the
campaign, it now prints a completion percentage and an estimated
remaining runtime along the usual progress reports.

The JobServer progress-report output now shows the total number of
completed jobs instead of the (almost always zero) inbound queue fill
level. Additionally, the current number of incoming results per
second is shown, which also prepares for an ETA calculation in the
following commit.

When prefixing a symbol name with '?', the GenericExperiment does not abort
in case the symbol is not found in the provided ELF binary:
fail-client -Wf,--detected-marker=?eddiErrorHandler
[...]
[GenericExperiment] ELF Symbol not found, ignoring: eddiErrorHandler

The JobClient now resolves the server IP once (lazily, when needed) instead
on each connect attempt, reducing the amount of DNS requests sent out.

The import-trace tool now systematically collects statistics on which
LLVM -> FAIL* register ID mappings failed during import, and presents
those after the import finished.
