815518dc02 add facility for incremental parsing #6123 
Adding new API object to maintain state between calls to parser.
The state is incremental: all declarations of sorts and functions are valid in the next parse. The parser produces an ast-vector of assertions that are parsed in the current calls.

The following is a unit test:

```
from z3 import *

pc = ParserContext()

A = DeclareSort('A')

pc.add_sort(A)
print(pc.from_string("(declare-const x A) (declare-const y A) (assert (= x y))"))
print(pc.from_string("(declare-const z A) (assert (= x z))"))

print(parse_smt2_string("(declare-const x Int) (declare-const y Int) (assert (= x y))"))

s = Solver()
s.from_string("(declare-sort A)")
s.from_string("(declare-const x A)")
s.from_string("(declare-const y A)")
s.from_string("(assert (= x y))")
print(s.assertions())
s.from_string("(declare-const z A)")
print(s.assertions())
s.from_string("(assert (= x z))")
print(s.assertions())
```

It produces results of the form

```
[x == y]
[x == z]
[x == y]
[x == y]
[x == y]
[x == y, x == z]
```
Thus, the set of assertions returned by a parse call is just the set of assertions added.
The solver maintains state between parser calls so that declarations made in a previous call are still available when declaring the constant 'z'.
The same holds for the parser_context_from_string function: function and sort declarations either added externally or declared using SMTLIB2 command line format as strings are valid for later calls.

7aa4fc2d8f fixing #5164 
overloading resolution has evolved a bit given how it inter-operates with automatic insertion of coercions, instantiation of polymorphic data-types, arrays as function spaces and other goodies. This is a rewrite of overloading resolution to disentangle the main components and allow them to cascade to give room for each-other.
