* src/split.c (usage, long_options, main): New options --number, --unbuffered, --elide-empty-files. (set_suffix_length): New function to auto increase suffix length to handle a specified number of files. (create): New function. Refactored from cwrite() and ofile_open(). (bytes_split): Add max_files argument to support byte chunking. (lines_chunk_split): New function. Split file into chunks of lines. (bytes_chunk_extract): New function. Extract a chunk of file. (of_info): New struct. Used by functions lines_rr and ofile_open to keep track of file descriptors associated with output files. (ofile_open): New function. Shuffle file descriptors when there are more output files than available file descriptors. (lines_rr): New function to distribute lines round-robin to files. (chunk_parse): New function. Parses K/N syntax. * tests/misc/split-bchunk: New test for byte chunking. * tests/misc/split-lchunk: New test for line delimited chunking. * tests/misc/split-rchunk: New test for round-robin chunking. * tests/Makefile.am: Reference new tests. * tests/misc/split-fail: Add failure scenarios for new options. * tests/misc/split-l: Fix a typo. s/ln/split/. * doc/coreutils.texi (split invocation): Document --number. * NEWS: Mention the new feature. * .mailmap: Map new email address for shortlog.
