* Added more checks for return values and null pointers.
* Removed some dead code and unused variables.
* Fixed handling of calls to exec() family functions. If this functions
fail we need to cleanup resources.
* URL dependency was removed from session handling code. URL object
was only needed to get session key from client request. This was
moved somewhere else to achive better code reusability.
* Added URL parsing functionality that can be used without URL object.
Fixed some compiler warnings when compiling with -Wextra
Thanks to Jan Jaeger's excellent bug report, made some changes
that should make it easier to build ShellInABox for OpenWRT.
