Before #25597 we had:
```
sage: fricas.Gamma(3/2).sage()
1/2*sqrt(pi)
```
but this is broken in Sage 9.3.

When Fricas uses abs() in its return value, this function is translated back to sage as a new symbolic, unevaluable function. See this sage-devel [post](https://groups.google.com/forum/#!topic/sage-…

The following should work:
```
sage: fricas("matrix [[1::PF 3, 2],[2, 0]]").sage().parent()
Full MatrixSpace of 2 by 2 dense matrices over Finite Field of size 3

Currently, long lines my get parsed wrong, as the leading double quote in the following example shows. This ticket makes the parsing (slightly) more robust.
```
sage: fricas.get_string("unparse((-…

Strings are not translated into proper Sage expressions for some functions:
```
sage: SR("sin(x)")
sin(x)
sage: type(_.operator())
sage: SR("arcsin(x)")
arcsin(x)
sage: type(_.operator())
