[boost] [TR1] Patches for BCB2006

Several TR1 tests are failing due to an old workaround that took swap
out of namespace std::tr1.

The latest compiler is much more compatibile the the overloads for
complex math, so updated that workaround too.

There were a few occurrences of the problem where BCB does not allow a
leading :: following the typename keyword.  These seem to be the
exception, rather than the rule, in the files so I simply removed the
:: for all compilers, rather than insert another borland workaround.

Diffs follow against 1_34_0 branch.  OK to commit?
[mainline, then merge to branch]
