Darshit Shah f04b680a08 Create an asynchronous progress bar ...

Give the progress bar its own thread and let it update the entire
display asynchronously at a specified time interval. The existing
implementation refreshes the progress bar for each network packet
downloaded. Over multiple downloader threads and a high speed network
connection this can lead to far too many redrawings of the screen. Also,
each of the downloader threads will block while trying to acquire the
thread mutex because another thread just retrieved a packet. While I
haven't profiled it, it seems like there would be extremely high lock
contention in the existing implementation. Instead, with a separate
thread, we can update all the progress bar slots simultaneously at
regular intervals.

    * bootstrap.conf: Include Gnulib module "ioctl"
    * include/libwget.h.in: Define always_inline, flatten and deprecated
	compiler attributes for both GCC and Clang
    * include/libwget.h.in: Export new functions wget_human_readable,
	wget_bar_register and wget_bar_deregister.
    * include/libwget.h.in (wget_http_response_t): Add new element
	"cur_downloaded" to struct. This element keeps a track of the raw
	number of bytes downloaded in the response
        (_wget_bar_ctx): Define new struct for storing the progress bar
	context.
    * libwget/bar.c: Fix display of downloaded ratio. Ensure it does not
	exceed 100% by comparing the raw downloaded bytes instead of
	uncompressed downloaded bytes.
	Add support for printing the filename and downloaded bytes to the
	progress bar.
    * libwget/http.c (wget_http_response_cb): Store the raw number of
	bytes downloaded from the network in the response data
    * libwget/utils.c (wget_human_readable): New function to convert an
	int value to a human readable string
    * src/bar.c: Use the entire screen width instead of just 70 columns
	for the progress bar.
	Provide methods to register and deregister a progress bar
	context
	(wget_bar_update_thread): New method for the progress bar thread
	to update the output periodically.
    * src/bar.h: Same
    * src/job.h: Move definition of struct DOWNLOADER from main.c to
        here
    * src/progress.h: Move definition of _body_callback_context from
        main.c to here
    * src/utils.c: Add new method to determine the width of the screen
    * src/utils.h: Same
    * src/wget.c: Use the new progress bar contexts. Update, register
    and deregister them
        (main): Deinit the progress bar only if it was enabled
    * src/Makefile.am: Add new files, progress.h, utils.c, utils.h
