mercurial.el: fix error on hg-read-rev() with small tip, and cleanups

* Fix error if tip revision is smaller than hg-rev-completion-limit

  If tip revision is 10, "hg log -r -100:tip" fails.

* Remove dependencies on cl package at runtime

  Quote from GNU Emacs Lisp Reference Manual, Emacs Lisp Coding Conventions:
  > * Please don't require the `cl' package of Common Lisp extensions at
  >   run time.  Use of this package is optional, and it is not part of
  >   the standard Emacs namespace.  If your package loads `cl' at run
  >   time, that could cause name clashes for users who don't use that
  >   package.

* Check XEmacs at compile time

  Since byte-compiled file is not portable between GNU Emacs and
  XEmacs, checking type of emacs can be done at compile time.  This
  reduces byte-compiler warnings.

* Defvar variables binded dynamically and used across functions

* Combine status output string to state symbol alist into a variable,
  and use char instead of string for key of state alist

* Make hg-view-mode as minor-mode

* Define keymaps as conventions
