vim-patch:3495497: patch 9.1.1212: too many strlen() calls in edit.c

Problem:  too many strlen() calls in edit.c
Solution: refactor edit.c and remove strlen() calls
          (John Marriott)

This commit attempts to make edit.c more efficient by:

- in truncate_spaces() pass in the length of the string.
- return a string_T from get_last_insert(), so that the length of the
  string is available to the caller.
- refactor stuff_insert():

  - replace calls to stuffReadbuff() (which calls STRLEN() on it's
    string argument) with stuffReadbuffLen() (which gets the length of
    it's string argument passed in).
  - replace call to vim_strrchr() which searches from the start of the
    string with a loop which searches from end of the string to find the
    last ESC character.

- change get_last_insert_save() to call get_last_insert() to get the
  last_insert string (the logic is in one place).
