The index-pack command has two progress meters: one for
"receiving objects", and one for "resolving deltas". You get
neither by default, or both with "-v".
But for a push through receive-pack, we would want only the
"resolving deltas" phase, _not_ the "receiving objects"
progress. There are two reasons for this.
One is simply that existing clients are already printing
"writing objects" progress at the same time. Arguably
"receiving" from the far end is more useful, because it
tells you what has actually gotten there, as opposed to what
might be stuck in a buffer somewhere between the client and
server. But that would require a protocol extension to tell
clients not to print their progress. Possible, but
complexity for little gain.
The second reason is much more important. In a full-duplex
connection like git-over-ssh, we can print progress while
the pack is incoming, and it will immediately get to the
client. But for a half-duplex connection like git-over-http,
we should not say anything until we have received the full
request. Anything we write is subject to being stuck in a
buffer by the webserver. Worse, we can end up in a deadlock
if that buffer fills up.
So our best bet is to avoid writing anything that isn't a
small fixed size until we've received the full pack.

Because the initial connectivity check for a cloned
repository can be slow, 0781aa4 (clone: let the user know
when check_everything_connected is run, 2013-05-03) added a
"fake" progress meter; we simply say "Checking connectivity"
when it starts, and "done" at the end, with nothing between.
Since check_connected() now knows how to do a real progress
meter, we can drop our fake one and use that one instead.

Connectivity checks have to traverse the entire object graph
in the worst case (e.g., a full clone or a full push). For
large repositories like linux.git, this can take 30-60
seconds, during which time git may produce little or no
output.
Let's add the option of showing progress, which is taken
care of by rev-list.

Unless the "quiet" flag is given, check_connected sends any
errors to the stderr of the caller (because the child
rev-list inherits that descriptor). However, server-side
callers may want to send these over a sideband channel
instead. Let's make that possible.

The number of variants of check_everything_connected has
grown over the years, so that the "real" function takes
several possibly-zero, possibly-NULL arguments. We hid the
complexity behind some wrapper functions, but this doesn't
scale well when we want to add new options.
If we add more wrapper variants to handle the new options,
then we can get a combinatorial explosion when those options
might be used together (right now nobody wants to use both
"shallow" and "transport" together, so we get by with just a
few wrappers).
If instead we add new parameters to each function, each of
which can have a default value, then callers who want the
defaults end up with confusing invocations like:
check_everything_connected(fn, 0, data, -1, 0, NULL);
where it is unclear which parameter is which (and every
caller needs updated when we add new options).
Instead, let's add a struct to hold all of the optional
parameters. This is a little more verbose for the callers
(who have to declare the struct and fill it in), but it
makes their code much easier to follow, because every option
is named as it is set (and unused options do not have to be
mentioned at all).
Note that we could also stick the iteration function and its
callback data into the option struct, too. But since those
are required for each call, by avoiding doing so, we can let
very simple callers just pass "NULL" for the options and not
worry about the struct at all.
While we're touching each site, let's also rename the
function to check_connected(). The existing name was quite
long, and not all of the wrappers even used the full name.

It's easy to ask rev-list to do a traversal that may takes
many seconds (e.g., by calling "--objects --all"). In theory
you can monitor its progress by the output you get to
stdout, but this isn't always easy.
Some operations, like "--count", don't make any output until
the end.
And some callers, like check_everything_connected(), are
using it just for the error-checking of the traversal, and
throw away stdout entirely.
This patch adds a "--progress" option which can be used to
give some eye-candy for a user waiting for a long traversal.
This is just a rev-list option and not a regular traversal
option, because it needs cooperation from the callbacks in
builtin/rev-list.c to do the actual count.

The check_everything_connected function takes a "quiet"
parameter which does two things if non-zero:
1. redirect rev-list's stderr to /dev/null to avoid
showing errors to the user
2. pass "--quiet" to rev-list
Item (1) is obviously useful. But item (2) is
surprisingly not. For rev-list, "--quiet" does not have
anything to do with chattiness on stderr; it tells rev-list
not to bother writing the list of traversed objects to
stdout, for efficiency. And since we always redirect
rev-list's stdout to /dev/null in this function, there is no
point in asking it to ever write anything to stdout.
The efficiency gains are modest; a best-of-five run of "git
rev-list --objects --all" on linux.git dropped from 32.013s
to 30.502s when adding "--quiet". That's only about 5%, but
given how easy it is, it's worth doing.

When we tried to fix in 58461bd (t1308: do not get fooled by symbolic
links to the source tree, 2016-06-02) an obscure case where the user
cd's into Git's source code via a symbolic link, a regression was
introduced that affects all test runs on Windows.
The original patch introducing the test case in question was careful to
use `$(pwd)` instead of `$PWD`.
This was done to account for the fact that Git's test suite uses shell
scripting even on Windows, where the shell's Unix-y paths are
incompatible with the main Git executable's idea of paths: it only
accepts Windows paths.
It is an awkward but necessary thing, then, to use `$(pwd)` (which gives
us a Windows path) when interacting with the Git executable and `$PWD`
(which gives the shell's idea of the current working directory in Unix-y
form) for shell scripts, including the test suite itself.
Obviously this broke the use case of the Git maintainer when changing
the working directory into Git's source code directory via a symlink,
i.e. when `$(pwd)` does not agree with `$PWD`.
However, we must not fix that use case at the expense of regressing
another use case.
Let's special-case Windows here, even if it is ugly, for lack of a more
elegant solution.
