Patch description:
Adds sage.libs.mpmath which provides wrapper functions and
monkey patches some internal mpmath functions for speed. Mpmath
functions can be called from Sage as follows (with forward
and backward conversions handled automatically):
{{{
sage: import sage.libs.mpmath.all as a
sage: a.call(a.hyp2f1, 2, 2/3, -1/2, 3+4*I)
-0.111907858412569 - 0.536467867510390*I
sage: a.call(a.hyp2f1, 2, 2/3, -1/2, 3+4*I, prec=100)
-0.11190785841256900204178259859 - 0.53646786751038954277574814099*I
}}}
Some partial support for direct conversion from Sage -> mpmath
is also implemented (this is not completely working yet).
Also providing a preliminary spkg (with current mpmath trunk) in this
issue.
