Patch to support to determine the number of args of the
gethostby{name,addr}_r functions.
Contributed by Juan Carlos Gomes IT#68 (apparently).

Also includes support for detecting ssleay in configure.in.

These functions require their arguments to be in the range of `unsigned char'.

Building tests/progs/*.c in the main build process.
==> Test-suite must be called by 'make test', or 'make test-bdb2'

Still requires user to workaround Solaris pthread_create in -lc issue.

Implementation no longer uses strtok_r(), it may be broken
or have an odd prototype.
Update configure not to check for strtok/strtok_r nor require
strtok_r to LDAP_API_FEATURE_X_OPENLDAP_REENTRANT.

when symbol being replaced was defined as a macro.

* Fixed unfree'd 'char *results' in all tcl_* functions (only unfree'd in
  certain cases, moved the free to the actual function) so no more mem
  leaks. Tested this with over 500,000 access's for testing :)
* Miscellaneous source style and tabulation fixes

Slight adaption of concurrency-test to enable even more writers/readers.
