Stefan Eissing 45f9ef5dd9 Improvements in OpenSSL Compat ERR Queue handling. ...

Configuration
- thread-local storaoge is selected when available
- '--enable-error-queue-per-thread' and '--disable-error-queue-per-thread' can
  be used as before to explicitly en-/disable the feature.

Implementation:
- with thread-local-storage, error queue is realized in one struct without
  allocations. Queue size is restricted to 16 entries (per thread), which
  is the same limit in OpenSSL 1.1.x.
- without thread-local-storage, all error queue operations are mutex locked
- wc_PeekErrorNodeLineData() and wc_GetErrorNodeErr() added for use by SSL
  functions to allow locked queue iterations/manipulations.
