My previous patch 5950ba9 ("lib/namespace: don't leak fd in error case")
was a step in the wrong direction. Instead of closing the opened file
descriptor in error case only, follow a better approach here and close
the fd as soon as it is not used anymore. This way the inelegant goto
statements can be dropped, and the fd leak in non-error case is fixed as
well.

Prefer using the POSIX constant PATH_MAX instead of the legacy BSD
derived MAXPATHLEN. The necessary includes for MAXPATHLEN and PATH_MAX
are <sys/param.h> and <limits.h>, respectively.

New netns_switch func moved to the lib/namespace.c from ip/ipnetns.c
so it can be used from the other tools for fast switching
network namespace.
