If no --decorate option is given, we default to auto-decoration. And
when that kicks in, cmd_log_init_finish() will unconditionally load the
decoration refs.
However, if we are using a user-format that does not include "%d" or
"%D", we won't show the decorations at all, so we don't need to load
them. We can detect this case and auto-disable them by adding a new
field to our userformat_want helper. We can do this even when the user
explicitly asked for --decorate, because it can't affect the output at
all.
This patch consistently reduces the time to run "git log -1 --format=%H"
on my git.git clone (with ~2k refs) from 34ms to 7ms. On a much more
extreme real-world repository (with ~220k refs), it goes from 2.5s to
4ms.

The comment only mentions "notes", but there are more fields now (and
I'm about to add another). Let's make it more general, and stick the
struct next to the function to make the list of possibilities obvious.
While we're touching this comment, let's also mention the behavior of
NULL, which some callers rely on (though in the long run, this global is
pretty nasty and probably should get moved into rev_info).

"git log --format='...'" learned "%(describe)" placeholder.
* rs/pretty-describe:
archive: expand only a single %(describe) per archive
pretty: document multiple %(describe) being inconsistent
t4205: assert %(describe) test coverage
pretty: add merge and exclude options to %(describe)
pretty: add %(describe)
Every %(describe) placeholder in $Format:...$ strings in files with the
attribute export-subst is expanded by calling git describe. This can
potentially result in a lot of such calls per archive. That's OK for
local repositories under control of the user of git archive, but could
be a problem for hosted repositories.
Expand only a single %(describe) placeholder per archive for now to
avoid denial-of-service attacks. We can make this limit configurable
later if needed, but let's start out simple.

As we would like to use this trailers logic in the ref-filter, it's
nice to get an invalid trailer argument. This will allow us to print
precise error message while using `format_set_trailers_options()` in
ref-filter.
For capturing the invalid argument, we changed the working of
`format_set_trailers_options()` a little bit.
Original logic does "break" and fell through in mainly 2 cases -
1. unknown/invalid argument
2. end of the arg string
But now instead of "break", we capture invalid argument and return
non-zero. And non-zero is handled by the caller.
(We prepared the caller to handle non-zero in the previous commit).
Capturing invalid arguments this way will also affects the working
of current logic. As at the end of the arg string it will return non-zero.
So in order to make things correct, introduced an additional conditional
statement i.e if encounter ")", do 'break'.

Refactored trailers formatting logic inside pretty.c to a new function
`format_set_trailers_options()`. This new function returns the non-zero
in case of unusual. The caller handles the non-zero by "goto trailers_out".
This change will allow us to reuse the same logic in other places.

The function 'format_sanitized_subject()' is responsible for
sanitized subject line in pretty.c
e.g.
the subject line
the-sanitized-subject-line
It would be a nice enhancement to `subject` atom to have the
same feature. So in the later commits, we plan to add this feature
to ref-filter.
Refactor `format_sanitized_subject()`, so it can be reused in
ref-filter.c for adding new modifier `sanitize` to "subject" atom.
Currently, the loop inside `format_sanitized_subject()` runs
until `\n` is found. But now, we stored the first occurrence
of `\n` in a variable `eol` and passed it in
`format_sanitized_subject()`. And the loop runs upto `eol`.

When commit subjects or authors have non-ASCII characters, git
format-patch Q-encodes them so they can be safely sent over email.
However, if the patch transfer method is something other than email (web
review tools, sneakernet), this only serves to make the patch metadata
harder to read without first applying it (unless you can decode RFC 2047
in your head). git am as well as some email software supports
non-Q-encoded mail as described in RFC 6531.
Add --[no-]encode-email-headers and format.encodeEmailHeaders to let the
user control this behavior.

Make it possible to write for example
git log --format="%H,%S"
where the %S at the end is a new placeholder that prints out the ref

Using %d might seem like an alternative but it only shows the ref for the last
commit in the branch.
