rev-parse: match @{upstream}, @{u} and @{push} case-insensitively

Change the revision parsing logic to match @{upstream}, @{u} & @{push}
case-insensitively.

Before this change supplying anything except the lower-case forms
emits an "unknown revision or path not in the working tree"
error. This change makes upper-case & mixed-case versions equivalent
to the lower-case versions.

The use-case for this is being able to hold the shift key down while
typing @{u} on certain keyboard layouts, which makes the sequence
easier to type, and reduces cases where git throws an error at the
user where it could do what he means instead.

These suffixes now join various other suffixes & special syntax
documented in gitrevisions(7) that matches case-insensitively. A table
showing the status of the various forms documented there before &
after this patch is shown below. The key for the table is:

 - CI  = Case Insensitive
 - CIP = Case Insensitive Possible (without ambiguities)
 - AG  = Accepts Garbage (.e.g. @{./.4.minutes./.})

Before this change:

    |----------------+-----+------+-----|
    | What?          | CI? | CIP? | AG? |
    |----------------+-----+------+-----|
    | @{<date>}      | Y   | Y    | Y   |
    | @{upstream}    | N   | Y    | N   |
    | @{push}        | N   | Y    | N   |
    |----------------+-----+------+-----|

After it:

    |----------------+-----+------+-----|
    | What?          | CI? | CIP? | AG? |
    |----------------+-----+------+-----|
    | @{<date>}      | Y   | Y    | Y   |
    | @{upstream}    | Y   | Y    | N   |
    | @{push}        | Y   | Y    | N   |
    |----------------+-----+------+-----|

The ^{<type>} suffix is not made case-insensitive, because other
places that take <type> like "cat-file -t <type>" do want them case
sensitively (after all we never declared that type names are case
insensitive). Allowing case-insensitive typename only with this syntax
will make the resulting Git as a whole inconsistent.

This change was independently authored to scratch a longtime itch, but
when I was about to submit it I discovered that a similar patch had
been submitted unsuccessfully before by Conrad Irwin in August 2011 as
"rev-parse: Allow @{U} as a synonym for
@{u}" (<1313287071-7851-1-git-send-email-conrad.irwin@gmail.com>).

branch_get_push: do not segfault when HEAD is detached

Move the detached HEAD check from branch_get_push_1() to
branch_get_push() to avoid setting branch->push_tracking_ref when
branch is NULL.

sha1_name: implement @{push} shorthand

In a triangular workflow, each branch may have two distinct
points of interest: the @{upstream} that you normally pull
from, and the destination that you normally push to. There
isn't a shorthand for the latter, but it's useful to have.

For instance, you may want to know which commits you haven't
pushed yet:

  git log @{push}..

Or as a more complicated example, imagine that you normally
pull changes from origin/master (which you set as your
@{upstream}), and push changes to your own personal fork
(e.g., as myfork/topic). You may push to your fork from
multiple machines, requiring you to integrate the changes
from the push destination, rather than upstream. With this
patch, you can just do:

  git rebase @{push}

rather than typing out the full name.

The heavy lifting is all done by branch_get_push; here we
just wire it up to the "@{push}" syntax.
