- bzlib: open file descriptors with O_CLOEXEC, but just like the zlib case, only when bzopen() is used and not bzdopen() to avoid messing up with the caller's semantics. It is responsability of to initiator to set that flag in such case. - Replace error prone list of exported symbols with proper use of GCC visibility features.
