*execvp.c - execute a file and search along PATH

*Purpose:
* defines _execvp() - execute a file and search along PATH

/***
*int _execvp(filename, argvector) - execute file; search along PATH
*
*Purpose:
* Execute the given file with given path and current environ.
* try to execute the file. start with the name itself (directory '.'),
* and if that doesn't work start prepending pathnames from the
* environment until one works or we run out. if the file is a pathname,
* don't go to the environment to get alternate paths. if errno comes
* back ENOEXEC, try it as a shell command file with up to MAXARGS-2
* arguments from the original vector. if a needed text file is busy,
* wait a little while and try again before despairing completely
* Actually calls _execvpe() to do all the work.
*
*Entry:
* _TSCHAR *filename - file to execute
* _TSCHAR **argvector - vector of arguments
*
*Exit:
* destroys the calling process (hopefully)
* if fails, returns -1
*
*Exceptions:
*
