This introduces a TermManager object, which will, in the future, be the
sole object responsible for handling/managing terms and sorts. For now,
all corresponding functions in `cvc5::Solver` are marked as deprecated,
as is constructor `cvc5::Solver::Solver()`, since in the future a solver
instance must be constructed from a term manager instance. Currently, we
maintain a static thread_local term manager instance to not break the
API and continue providing constructor `cvc5::Solver::Solver()`.
Note that this already converts all C++ unit tests to use the
TermManager except for a single test `getStatistics()` in
`test/unit/api/cpp/solver_black.cpp`. Statistics handling is currently
still maintained on the solver level. The statistics we maintain,
however, concern terms only and will eventually be refactored to be
tracked in the NodeManager.
Further note that the Java and Python APIs will be refactored in
separate PRs.
This introduces a general way to use public enums both in the C++ and
the (upcoming) C API. For the C++ case, we now use enum classes rather
than enums for public enums. This also includes definitions for
C API to_string conversions for public enums. C API definitions in
cvc5_types.h are only included from the C API, guarded via a macro
(thus, for now, not included yet when the header is included).
This PR adds the code for printing synthesis solutions to the docs. Various other changes are made to increase the consistency between the different bindings.

The public cvc5 API now lives in the cvc5 namespace. All internal parts were moved into the (new) internal namespace.
The final hierarchy will be as follows:
cvc5
~~ public API
::context
::internal
::parser
::main
After this PR it will be:
cvc5
~~ public API
::internal
::context
::main
::parser
Also extends to non-trivial unit test of SynthResult.
Note this also changes the expected output when using --sygus-out=status from unsat/sat/unknown to feasible/infeasible/fail (the option is used mostly just for our regressions). The output mode status-or-def is now equivalent to standard and is hence deleted.
This commit ensures we don't segfault in the SyGuS API (for non-text inputs) if the option sygus is not set to true. It also renames mkSygusVar to declareSygusVar for consistency with the sygus input format.
For SyGuS API inputs, we now use the option sygus to true instead of setting the language to sygus2.
This furthermore changes a few details in set-defaults regarding the relationship between the language, the sygus option, and when to apply default options for sygus.
It also adds a unit test for checkSynth.
This renames the arithmetic internal and API kind PLUS to ADD for
consistency with our naming scheme for other operators (e.g.,
BITVECTOR_ADD, FLOATINGPOINT_ADD).
This PR adds (most of) the existing examples to the documentation, and does some other minor updates on the documentation. Some details:
- for consistency, all cpp examples are moved from examples/api to examples/api/cpp
- add capabilities for SMT-LIB examples, and two simple smt2 examples
- more docs/examples/*.rst files
- two new documentation categories: installation (how to obtain, compile and install cvc5) and binary (about the cvc5 binary)
