Log Message:
wip/nlopt: Upgrade of math/nlopt from 2.4.2 to 2.6.2.

pkgsrc Makefile substitution to prefix builtin rb_tree symbols to
avoid collisions against NetBSD libc rbtree.

Tested with wip/PrusaSlicer.

Release notes:

2.6.2:
 - Fixed forced stop exception with dimension elimination ([#317])
 - Fixed get_initial_step wrapping ([#319])
 - Various build fixes ([#314], [#308], [#303], [#278])

2.6.1:
 - Fix nlopt_version return value for 2.6.x and update soname and docs.

2.6.0:
 - New set_upper_bound and set_lower_bound functions in the low-level C API
   to set one bound at a time (#257). There is no longer a separate
   libnlopt_cxx library - C++ algorithms (stogo) are compiled and included
   by default (#198). Various build fixes (#197, #216, #245, #250, #230,
   #261, etc.), other fixes (#242, #258).

2.5.0:
 - New AGS global solver (#194), thanks to Vladislav Sovrasov.
 - New nlopt_get_numevals function providing a built-in evaluation counter
   (#160).
 - New nlopt_get_errmsg function for more descriptive error messages.
 - Build system is converted to cmake (#49), thanks to Julien Schueller
 - Plugins updated for recent Octave and Guile versions.
 - Various other build fixes and minor bug fixes.

+NLopt is a free/open-source library for nonlinear optimization,
+providing a common interface for a number of different free optimization
+routines available online as well as original implementations of various
+other algorithms.
+
+Its features include:
+- Callable from C, C++, Fortran, Matlab or GNU Octave, Python,
+  GNU Guile, Julia, GNU R, Lua, and OCaml.
+- A common interface for many different algorithms -- try a different
+  algorithm just by changing one parameter.
+- Support for large-scale optimization (some algorithms scalable to
+  millions of parameters and thousands of constraints).
+- Both global and local optimization algorithms.
+- Algorithms using function values only (derivative-free) and also
+  algorithms exploiting user-supplied gradients.
+- Algorithms for unconstrained optimization, bound-constrained
+  optimization, and general nonlinear inequality/equality constraints.
