Broken exec and eval in Boost.Python 1.65.1

[Vaclav Blazek]

Boost.Python v. 1.65.0 introduced overloaded functions eval and exec for const char* while the original (str) functions call these overloads.

However, global and local context is not forwarded from str version to const char* and executed Python code sees empty global context making it unable to use any built-in Python function.

The erroneous upstream code was NOT fixed in 1.65.1, used in Ubuntu 18.04, making any software depending on Boost.Python's exec/eval broken on 18.04.

Upstream fixed the code in the next release (1.66.0):
https://github.com/boostorg/python/commit/b09d80a93e299bdaba29b652010b668b87f1306c

Would it be possible to incorporate this patch in the 18.04 LTS?
