Subject: core: add option weechat.look.buffer_auto_renumber

New option: weechat.look.buffer_auto_renumber, boolean which is on by
default, so the behavior is the same: no gap is allowed in numbers,
they start at number 1 and they are auto-renumbered after each command
like /buffer move, /buffer merge, ...

A new option "renumber" has been added in command /buffer, to renumber
a range of buffers (or all).

Changes when the option weechat.look.buffer_auto_renumber is off:

- command "/buffer move":
    - the current number will be left free for use, and the
      target number can be any number >= 1 (possibly higher than the
      current last buffer number)
    - the value can be "-" (which moves the buffer to number 1)
      or "+" (which moves the buffer to the end, ie last number + 1)

- command "/buffer swap":
    - now the buffers are swapped in the list without being "moved"

- comand "/buffer [+/-]N":
    - it is now working with gaps in buffer numbers

- command "/buffer merge":
    - it can now merge a group of merged buffers into another buffer
      (or buffers merged themselves)

- layout can restore buffer numbers with gaps in numbers
