git-send-email: introduce compose-encoding

The introduction email (--compose option) have encoding hardcoded to
UTF-8, but invoked editor may not use UTF-8 encoding.
The encoding used by patches can be changed by the "8bit-encoding"
option, but this option does not have effect on introduction email
and equivalent for introduction email is missing.

Added compose-encoding command line option and sendemail.composeencoding
configuration option specify encoding of introduction email.

Allow __git_ps1 to be used in PROMPT_COMMAND

Changes __git_ps1 to allow its use as PROMPT_COMMAND in bash
in addition to setting PS1 with __git_ps1 in a command substitution.
PROMPT_COMMAND has advantages for using color without running
into prompt-wrapping issues. Only by assigning \[ and \] to PS1
directly can bash know that these and the enclosed zero-width codes in
between don't count in the length of the prompt.

show color hints based on state of the git tree

By setting GIT_PS1_SHOW_COLORHINTS when using __git_ps1
as PROMPT_COMMAND, you will get color hints in addition to
a different character (*+% etc.) to indicate the state of
the tree.

exclude: stricten a length check in EXC_FLAG_ENDSWITH case

This block of code deals with the "basename" part only, which has the
length of "pathlen - (basename - pathname)". Stricten the length check
and remove "pathname" from the main expression to avoid confusion.

exclude: fix a bug in prefix compare optimization

When "namelen" becomes zero at this stage, we have matched the fixed
part, but whether it actually matches the pattern still depends on the
pattern in "exclude". As demonstrated in t3001, path "three/a.3"
exists and it matches the "three/a.3" part in pattern "three/a.3[abc]",
but that does not mean a true match.

Don't be too optimistic and let fnmatch() do the job.

attr: more matching optimizations from .gitignore

.gitattributes and .gitignore share the same pattern syntax but has
separate matching implementation. Over the years, ignore's
implementation accumulates more optimizations while attr's stays the
same.

This patch reuses the core matching functions that are also used by
excluded_from_list. excluded_from_list and path_matches can't be
merged due to differences in exclude and attr, for example:

* "!pattern" syntax is forbidden in .gitattributes.  As an attribute
  can be unset (i.e. set to a special value "false") or made back to
  unspecified (i.e. not even set to "false"), "!pattern attr" is unclear
  which one it means.

* we support attaching attributes to directories, but git-core
  internally does not currently make use of attributes on
  directories.

refs: lock symref that is to be deleted, not its target

When delete_ref is called on a symref then it locks its target and then
either deletes the target or the symref, depending on whether the flag
REF_NODEREF was set in the parameter delopt.

Instead, simply pass the flag to lock_ref_sha1_basic, which will then
either lock the target or the symref, and delete the locked ref.

This reimplements part of eca35a25 (Fix git branch -m for symrefs.).

Fix up colored git-prompt

The main point is to match the colors to be more close to the color
output of "git status -sb".

 - the branchname is green, or in red when the HEAD is detached;

 - the flags are either red or green for unstaged/staged and the
   remaining flags get a different color or none at all.

sha1Or-k was a vestige from an early, never-released

Ultimately it wasn't needed, and I should have gotten rid of it
