Switch to MiB/s when the connection is fast enough (i.e. on a LAN).

66913284f0 progress bar: round to the nearest instead of truncating down
Often the throughput output is requested when the data read so far is
one smaller than multiple of 1024; because 1023/1024 is ~0.999, it often
shows up as 0.99 because the code currently truncates.

d4c44443b6 progress.c: avoid use of dynamic-sized array
Dynamically sized arrays are gcc and C99 construct.  Using them hurts
portability to older compilers, although using them is nice in this case
it is not desirable.  This patch removes the only use of the construct
in stop_progress_msg(); the function is about writing out a single line
of a message, and the existing callers of this function feed messages
of only bounded size anyway, so use of dynamic array is simply overkill.

137a0d0ef5 Flush progress message buffer in display().
This will make progress display from pack-objects (invoked via
upload-pack) more responsive on platforms with an implementation
of stdio whose stderr is line buffered.

The standard error stream is defined to be merely "not fully
buffered"; this is different from "unbuffered".  If the
implementation of the stdio library chooses to make it line
buffered, progress reports that end with CR but do not contain
LF will accumulate in the stdio buffer before written out.  A
fflush() after each progress display gives a nice continuous
progress.

a984a06a07 nicer display of thin pack completion
In the same spirit of prettifying Git's output display for mere mortals,
here's a simple extension to the progress API allowing for a final
message to be provided when terminating a progress line, and use it for
the display of the number of objects needed to complete a thin pack,
saving yet one more line of screen display.

53ed7b5a5d make display of total transferred fully accurate
The minimum delay of 1/2 sec between successive throughput updates might
not have been elapsed when display_throughput() is called for the last
time, potentially making the display of total transferred bytes not
right when progress is said to be done.

Let's force an update of the throughput display as well when the
progress is complete.  As a side effect, the total transferred will
always be displayed even if the actual transfer rate doesn't have time
to kickin.

218558af59 make display of total transferred more accurate
The throughput display needs a delay period before accounting and
displaying anything.  Yet it might be called after some amount of data
has already been transferred.  The display of total data is therefore
accounted late and therefore smaller than the reality.

Let's call display_throughput() with an absolute amount of transferred
data instead of a relative number, and let the throughput code find the
relative amount of data by itself as needed.  This way the displayed
total is always exact.

81f6654a47 Show total transferred as part of throughput progress
Right now it is infeasible to offer to the user a reasonable concept
of when a clone will be complete as we aren't able to come up with
the final pack size until after we have actually transferred the
entire thing to the client.  However in many cases users can work
with a rough rule-of-thumb; for example it is somewhat well known
that git.git is about 16 MiB today and that linux-2.6.git is over
120 MiB.

We now show the total amount of data we have transferred over
the network as part of the throughput meter, organizing it in
"human friendly" terms like `ls -h` would do.  Users can glance at
this, see that the total transferred size is about 3 MiB, see the
throughput of X KiB/sec, and determine a reasonable figure of about
when the clone will be complete, assuming they know the rough size
of the source repository or are able to obtain it.

This is also a helpful indicator that there is progress being made
even if we stall on a very large object.  The thoughput meter may
remain relatively constant and the percentage complete and object
count won't be changing, but the total transferred will be increasing
as additional data is received for this object.

[from an initial proposal from Shawn O. Pearce]

3e935d1982 make sure throughput display gets updated even if progress doesn't move
Currently the progress/throughput display update happens only through
display_progress().  If the progress based on object count remains
unchanged because a large object is being received, the latest throughput
won't be displayed.  The display update should occur through
display_throughput() as well.

throughput when that makes sense.

96a02f8f6d common progress display support
Instead of having this code duplicated in multiple places, let's have
a common interface for progress display.  If someday someone wishes to
display a cheezy progress bar instead then only one file will have to
be changed.

Note: I left merge-recursive.c out since it has a strange notion of
progress as it apparently increase the expected total number as it goes.
Someone with more intimate knowledge of what that is supposed to mean
might look at converting it to the common progress interface.
