[sanitizer_common] Implement popen, popenve, pclose interceptors
Implement the interceptors for popen(), pclose() and popenve()
functions. The first two are POSIX, the third one is specific
to NetBSD. popen() spawns a process and creates a FILE object piping
data from/to that process. pclose() closes the pipe and waits for
the process to terminate appropriately.
For the purpose of popen(), the COMMON_INTERCEPTOR_FILE_OPEN macro is
modified to allow null path parameter.
