gdb: Use std::min and std::max throughout

Otherwise including <string> or some other C++ header is broken.
E.g.:

  In file included from /opt/gcc/include/c++/7.0.0/bits/char_traits.h:39:0,
		   from /opt/gcc/include/c++/7.0.0/string:40,
		   from /home/pedro/gdb/mygit/cxx-convertion/src/gdb/infrun.c:68:
  /opt/gcc/include/c++/7.0.0/bits/stl_algobase.h:243:56: error: macro "min" passed 3 arguments, but takes just 2
       min(const _Tp& __a, const _Tp& __b, _Compare __comp)
							  ^
  /opt/gcc/include/c++/7.0.0/bits/stl_algobase.h:265:56: error: macro "max" passed 3 arguments, but takes just 2
       max(const _Tp& __a, const _Tp& __b, _Compare __comp)
							  ^
  In file included from .../src/gdb/infrun.c:21:0:

To the best of my grepping abilities, I believe I adjusted all min/max
calls.
