Use CXXFLAGS when compiling parsers (#197)
ANTLR generates C files that we compile with the C++ compiler.
To do so, we set CC=CXX in the `Makefile.am`s of the parsers.
Previously, we did not copy the CXXFLAGS to the CFLAGS, which
could result in problems, e.g. when using -std=gnu++11 in the
CXXFLAGS, compiling the parsers would fail if they used C++11
features (configure.ac usually modifies CXX to include the
-std=gnu++11 flag but if it is included in CXXFLAGS, the CXX
is not changed).

Avoid invoking copy constructor when safe printing (#184)
When CVC4 gets interrupted, we use async-signal safe printing functions
to print statistics. Unfortunately, the code for that was invoking copy
constructors, which is problematic due to memory allocation; for example
with statistics such as ReferenceStat<std::string>. This commit adds a
getDataRef() method for statistics that returns a const reference to the
object being printed such that the copy constructor is not called. Note:
modifying getData() was unfortunately not an option because in the case
of TimerStat, we can't return a reference to an object on the stack. We
could remove the const modifier on getData() and use d_data to store the
information but then we would have to remove it on
safeFlushInformation() and potentially other methods as well, which
seems like a worse solution.

Fix stream parsing
This commit fixes bug 811. Bug 811 was caused because tokens were referring to
a buffer that was reallocated and thus the pointers were not valid anymore.
Background:
The buffered input stream avoids copying the whole input stream before handing
it to ANTLR (in contrast to the non-buffered input stream that first copies
everything into a buffer). This enables interactivity (e.g. with kind2) and may
save memory.
CVC4 uses it when reading from stdin in competition mode for the application
track (the incremental benchmarks) and in non-competition mode. To set the
CVC4_SMTCOMP_APPLICATION_TRACK flag, the {C,CXX}FLAGS have to be modified at
configure time.
Solution:
This commit fixes the issue by changing how a stream gets buffered. Instead of
storing the stream into a single buffer, CVC4 now stores each line in a
separate buffer, making sure that they do not have to move, keeping tokens
valid. The commit adds the LineBuffer class for managing those buffers. It
further modifies CVC4's LA and consume functions to use line number and
position within a line to index into the line buffer. This allows us to use the
standard mark()/etc. functions because they automatically store and
restore that state. The solution also (arguably) simplifies the code.
Disadvantages:
Tokens split across lines would cause problems (seems reasonable to me). One
allocation per line.
Alternatives considered:
Pull request 162 by Tim was a first attempt to solve the problem. The issues
with this solution are: memory usage (old versions of the buffer do not get
deleted), tokens split across buffers would be problematic, and
mark()/rewind()/etc. would have to be overwritten for the approach to work.
I had a partially working fix that used indexes into the stream instead of
pointers to memory. The solution stored the content of the stream into a
segmented buffer (lines were not guaranteed to be consecutive in memory. This
approach was working for basic use cases but had the following issues: ugly
casting (the solution requires casting the index to a pointer and storing it in
the input stream's nextChar because that's where ANTLR is taking the location
information from when creating a token), more modifications (not only would
this solution require overwriting more functions of the input stream such as
substr, it also requires changes to the use of GETCHARINDEX() in the Smt2
parser and AntlrInput::tokenText() for example), more complex code.

[Competition] Fix ABC, fix CryptoMiniSat req
This commit fixes two issues that caused the competition configuration to fail on the cluster machines:
We used an ancient version of ABC that declared a function (factorial()
luckySimple.c) in a source file as inline but not static. This issue was fixed
in the following commit:
https://bitbucket.org/alanmi/abc/commits/
e0aa7af0d73538fb786c4dcc72745578f0068a38
The issue with non-static inline functions in source files is described in the
following Stackoverflow post:
https://stackoverflow.com/questions/
16740515/simple-c-inline-linker-error
This commit updates ABC to a much newer version (commit tagged as
abc20160717),
which fixes the issue. One of the modifications previously performed by
contrib/get-abc does not need to be necessary anymore.
CryptoMiniSat was always linked against m4ri, even though it was not getting
compiled with it (-DNOM4RI="ON" in contrib/get-cryptominisat4). This commit
removes the part of config/cryptominisat.m4 that explicitly sets the libraries
linked to and instead uses the result of CVC4_TRY_CRYPTOMINISAT_WITH (which
seems to work even though there is comment indicating otherwise). Further, it
adds -pthread to the libraries required by CryptoMiniSat because it is required
by the version of CryptoMiniSat that we use (a newer version supports disabling
that behavior, so it might be a good idea to update). Previously, this would
lead to linker errors.

version instead of the std::string version of safe_print.
Finally, this fixes an issue where --segv-spin would not print the program name
because it was a const char*. The program name is now stored as a string.
NOTE: As a side effect, the last part also fixes Coverity issue
1362944, which
has been in CVC4 for a long time.

Fix type checks for relation operators
This commit fixes an assertion error when applying transpose or transitive
closure to a set instead of a relation. Instead it now prints a parse error.

Fix minor bug in sets rewriter
As reported by Coverity, one of the switches in the sets rewriter had a missing
break. This could lead to an assertion failure when rewriting the cardinality
of a transpose as in the test case included in this commit.
