Merge changes to main(), urlParse() and streamPlaylist(). In main():
* Install the signal handler as late as possible. * Add new command line options: -v (verbose, use twice for even more verbose output) and -q (quiet, redirect standard error output from external de-/ encoders to /dev/null.) * It is now an error to supply more than one -c parameter. This prevents unexpected results. * Add a stern warning when ezstream is running as root. Just Don't Do It. Leaving the configfile writeable to others by accident could mean instant root compromise. * Before handing the config file over to libxml, try to open it ourselves first. The error message from strerror() is a lot more helpful than the cryption I/O error printed by libxml. * Don't preallocate memory for urlParse(). * Fix command line error messages, they seem to be for a different program than Ezstream. * More terse libshout error messages, just print which function failed. I consider these errors of questionable value for an end user, but at least a knowledgeable one will know instantly what went wrong. * Case insensitive matching of playlist file extensions. * Print the address, port and mountpoint that Ezstream is actually trying to connect to, instead of what the user supplied. That should make it easier to spot reasons for connect failures (e.g. typos.) Changes in urlParse(): * Let urlParse() allocate memory for hostname and mountpoint, as it knows how much memory is actually required. * Fix a buffer overflow of the tmpPort buffer by adding checks and using safe string functions. * Let the caller print an error message, instead of having the same printf() twice in urlParse(). The streamPlaylist() function has been rewritten to use the new playlist_*() routines. Apart from the added playlist shuffle feature no functional change. git-svn-id: https://svn.xiph.org/trunk/ezstream@12552 0101bb08-14d6-0310-b084-bc0e0c8e3800
