remove support for the 'L' (fmt/flow-paragraph) command

* sed/Makefile.am (sed_SOURCES): Remove fmt.c.
* sed/execute.c (execute_program):
* sed/fmt.c: Remove file.
* sed/sed.h (fmt): Remove declaration.
* doc/sed.texi: Remove documentation for 'L' command.
* doc/sed-in.texi: Likewise.
* NEWS (Feature removal): Document it.
Prompted by the report from Jodie Cunningham that using this
command with a large number could cause sed to segfault:
