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.

The now commented-out variant that was introduced in commit be9d291
(when FAIL* was still in an SVN repo, r1702) may be necessary for some
specific system behavior after modifying the currently executed
instruction, but breaks random-jump FI (import-trace -i
RandomJumpImporter).

With GCC 9, some of the stdlibc++'s header files don't compile with
AspectC++ anymore. Until this is resolved, we compile with -std=c++11
although we actually use C++14 features; we need to ignore the
warnings pointing this out until AspectC++ works with these header
files.

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.

Implemented two instantiations of Fault-Space Regions (FSR) as a program-structure-guided approximation of fault spaces based on the precise Def/Use-Pruning using basic blocks or function calls.

Some configurations for bochs and generic-experiment
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
std::chrono::steady_clock for interval measurements.

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.
