openssl.c: make damn sure e_os.h knows about OPENSSL_C

eliminate some of the -Wcast-qual warnings (debug-ben-strict target)

except for the BIO through which we print the memory leak list,

from MemCheck_start() to CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON)
because that is what applications should use
(MemCheck_start/stop never really worked for applications
unless CRYPTO_MDEBUG was defined both when compiling the library
and when compiling the application, so probably we should
get rid of it).

`openssl' and second, the shortcut symlinks for the `openssl <command>' are no

repository copy, i.e. they still contain the complete file history.
