Merge changes to the remaining two functions, openResource() and streamFile(),
after which the merge is complete. Changes in openResource(): * Let the caller know whether we're streaming from standard input, and give it a copy of the metadata information. * Make filename extension matching case insensitive. Ezstream can now stream foo.Ogg out of playlist.tXt. (On that note, another item from the parseConfig() commit log message was missing: <format/> and <match/> are also case insensitive now.) Changes in streamFile(): * New feature: Skip currently playing track when receiving SIGUSR1. * New feature: When using both the new -q and -v command line parameters, Ezstream now displays some "real-time" information: playlist position, elapsed time streaming the current track, and approximate bitrate in kbps. * Fix the fread() loop by moving the "if read bytes > 0" condition into the while statement, and check with ferror() afterwards whether an error occured. * Remove redundant shout_delay() call. Ezstream puts itself to sleep with shout_sync(). * Return a value that makes sense in main()'s do-while loop, instead of whatever shout_send() returned last. * Remove or prettify a few messages. git-svn-id: https://svn.xiph.org/trunk/ezstream@12557 0101bb08-14d6-0310-b084-bc0e0c8e3800
