man.vim: rewrite

- Smart autocomplete. It's automatically sorted, filtered for duplicates
  and even formats the candidates based on what is needed. For example,
  `:Man 1 printf<TAB>` will show the pages that are in section 1m as
  'page(sect)' to let you know they are in a more specific section.
- Instead of trying to unset $MANPAGER we use the -P flag to set the
  pager to cat
- Always use the section arg '-s', it makes the code much simpler
  (see comment in s:man-args).
- A manpage name starting with '-' is invalid. It's fine for sections
  because of the use of '-s'.

- The tagstack is an actual stack now, makes it much simpler.
- By using v:count and v:count1, the plugin can explicitly check whether
  the user set a count, instead of relying on a default value (0) that
  is actually a real manpage section.
- Extraction of a manpage reference is much more simple. No giant long
  complicated regexes. Now, the plugin lets `man` handle the actual
  validation. We merely extract the section and page. Syntax regexes are
  a bit more specific though to prevent highlighting everything.
- Multilingual support in the syntax file. Removed the cruft that was only
  relevent to vim. Also simplified and improved many of the regexes.

- Using shellescape when sending the page and sect as arguments
- In general, the code flow is much more obvious.
- man#get_page has been split up into smaller functions with explicit
  responsibilties
- ':help' behavior in opening splits and manpages
- Comments explaining anything that needs explaining and isn't
  immediately obvious.
- If a manpage has already been loaded but if it were to reloaded at the
  current width which is the same as the width at which it was loaded at
  previously, it is not reloaded.

- Use substitute to remove the backspaced instead of `col -b`, as the
  latter doesn't work with other languages.
- Open paths to manpages
- It uses cWORD instead of cword to get the manpage under the cursor, this
  helps with files that do not have (,) in iskeyword. It also means the
  plugin does not set iskeyword locally anymore.
- <Plug>(Man) mapping for easy remapping
- Switched to single quotes wherever possible.
- Updated docs in $VIMRUNTIME/doc/filetype.txt (still need to update
  user-manual)

- Always call tolower on section name. See comment in
  s:extract_page_and_sect_fpage
- Formatting/consistency cleanup
- Automatically map q to ':q<CR>' when invoked as $MANPAGER
- It also fully supports being used as $MANPAGER. Setting the name and
  stuff automatically.
- Split up the setlocals into multiple lines for easier readability
- Better detection of errors by redirecting stderr to /dev/null. If an
  error occured, stdout will be empty.

- Functions return [sect, page] not [page, sect]. Makes more sense with
  how man takes the arguments as sect and then page.
- Pretty prints errors on a single line.
- If no section is given, automatically finds the correct section for
  the buffer name. It also gets the correct page. See the comment in
  s:get_page
- If $MANWIDTH is not set, do not assign directly to $MANWIDTH because
  then $MANWIDTH will always stay set to the same value as we only use
  winwidth(0) when the global $MANWIDTH is empty. Instead we set it
  locally for the command.
- Maintainer notes on all files.

Display the manual page for {name} in a section {number}.
Man {name} Display the manpage for {name} in a new tab.
Man {sect} {name} Same as above except specify the section.
