Because of the wrapping of the branch name variable $b, the colour codes
in the variable don't get applied, but are instead printed directly in
the output. Move the wrapping of $b to before colour codes are inserted
to correct this. Revert move of branch name colour codes in tests, as
the branch name is now coloured after the wrapping instead of before.

The short upstream state indicator inherits the colour of the last short
state indicator before it (if there is one), and the sparsity state
indicator inherits this colour as well. This behaviour was introduced by
0ec7c23cdc (git-prompt: make upstream state indicator location
consistent, 2022-02-27), while before this change the aforementioned
indicators were white/the default text colour. Some examples to
illustrate this behaviour (assuming all indicators are enabled and
colourization is on):
* If there is something in the stash, both the '$' and the short
upstream state indicator following it will be blue.
* If the local tree has new, untracked files and there is nothing in
the stash, both the '%' and the short upstream state indicator
will be red.
* If all local changes are added to the index and the stash is empty,
both the '+' and the short upstream state indicator following it will
be green.
* If the local tree is clean and there is nothing in the stash, the
short upstream state indicator will be white/${default text colour}.
This appears to be an unintended side-effect of the change, and makes
little sense semantically (e.g. why is it bad to be in sync with
upstream when you have uncommitted local changes?). The cause of the
change in colourization is that previously, the short upstream state
indicator appeared immediately after the rebase/revert/bisect/merge
state indicator (note the position of $p in $gitstring):
local f="$h$w$i$s$u"
local gitstring="$c$b${f:+$z$f}${sparse}$r$p"
Said indicator is prepended with the clear colour code, and the short
upstream state indicator is thus also uncoloured. Now, the short
upstream state indicator follows the sequence of colourized indicators,
without any clearing of colour (again note the position of $p, now in
$f):
local f="$h$w$i$s$u$p"
local gitstring="$c$b${f:+$z$f}${sparse}$r${upstream}"
If the user is in a sparse checkout, the sparsity state indicator
follows a similar pattern to the short upstream state indicator.
However, clearing colour of the colourized indicators changes how the
sparsity state indicator is colourized, as it currently inherits (and
before the change referenced also inherited) the colour of the last
short state indicator before it. Reading the commit message of the
change that introduced the sparsity state indicator, afda36dbf3
(git-prompt: include sparsity state as well, 2020-06-21), it appears
this colourization also was unintended, so clearing the colour for said
indicator further increases consistency.
Make the colourization of these state indicators consistent by making
all colourized indicators clear their own colour. Make colouring of $c
dependent on it not being empty, as it is no longer being used to colour
the branch name. Move clearing of $b's prefix to before colourization so
it gets cleared properly when colour codes are inserted into it. These
changes make changing the layout of the prompt less prone to unintended
colour changes in the future.
Change coloured Bash prompt tests to reflect the colourization changes:
* Move the colour codes to wrap the expected content of the expanded
$__git_ps1_branch_name in all tests.
* Insert a clear-colour code after the symbol for the first indicator
in "prompt - bash color pc mode - dirty status indicator - dirty
index and worktree", to reflect that all indicators should clear
their own colour.

In http.c, the run_active_slot() function allows the given "slot" to
make progress by calling step_active_slots() in a loop repeatedly,
and the loop is not left until the request held in the slot
completes.
Ages ago, we used to use the slot->in_use member to get out of the
loop, which misbehaved when the request in "slot" completes (at
which time, the result of the request is copied away from the slot,
and the in_use member is cleared, making the slot ready to be
reused), and the "slot" gets reused to service a different request
(at which time, the "slot" becomes in_use again, even though it is
for a different request). The loop terminating condition mistakenly
thought that the original request has yet to be completed.
Today's code, after baa7b67d (HTTP slot reuse fixes, 2006-03-10)
fixed this issue, uses a separate "slot->finished" member that is
set in run_active_slot() to point to an on-stack variable, and the
code that completes the request in finish_active_slot() clears the
on-stack variable via the pointer to signal that the particular
request held by the slot has completed. It also clears the in_use
member (as before that fix), so that the slot itself can safely be
reused for an unrelated request.
One thing that is not quite clean in this arrangement is that,
unless the slot gets reused, at which point the finished member is
reset to NULL, the member keeps the value of &finished, which
becomes a dangling pointer into the stack when run_active_slot()
returns. Clear the finished member before the control leaves the
function, which has a side effect of unconfusing compilers like
recent GCC 12 that is over-eager to warn against such an assignment.

Technically, the pointer difference `end - start` _could_ be negative,
and when cast to an (unsigned) `size_t` that would cause problems. In
this instance, the symptom is:
dir.c: In function 'git_url_basename':
dir.c:3087:13: error: 'memchr' specified bound [9223372036854775808, 0]

[-Werror=stringop-overread]
CC ewah/bitmap.o
3087 | if (memchr(start, '/', end - start) == NULL
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
While it is a bit far-fetched to think that `end` (which is defined as
`repo + strlen(repo)`) and `start` (which starts at `repo` and never
steps beyond the NUL terminator) could result in such a negative
difference, GCC has no way of knowing that.
See also https://gcc.gnu.org/bugzilla//show_bug.cgi?id=85783.
Let's just add a safety check, primarily for GCC's benefit.

Git for Windows' SDK recently upgraded to GCC v12.x which points out
that the `pos` variable might be used even after the corresponding
memory was `realloc()`ed and therefore potentially no longer valid.
Since a subset of this SDK is used in Git's CI/PR builds, we need to fix
this to continue to be able to benefit from the CI/PR runs.
Note: This bug has been with us since 2a6b149c64 (mingw: avoid using
strbuf in syslog, 2011-10-06), and while it looks tempting to replace
the hand-rolled string manipulation with a `strbuf`-based one, that
commit's message explains why we cannot do that: The `syslog()` function
is called as part of the function in `daemon.c` which is set as the
`die()` routine, and since `strbuf_grow()` can call that function if it
runs out of memory, this would cause a nasty infinite loop that we do
not want to re-introduce.
