Merge branch 'jc/peace-with-crlf'

Many commands that read files that are expected to contain text
that is generated (or can be edited) by the end user to control
their behaviour (e.g. "git grep -f <filename>") have been updated
to be more tolerant to lines that are terminated with CRLF (they
used to treat such a line to contain payload that ends with CR,
which is usually not what the users expect).

* jc/peace-with-crlf:
  test-sha1-array: read command stream with strbuf_getline()
  grep: read -f file with strbuf_getline()
  send-pack: read list of refs with strbuf_getline()
  column: read lines with strbuf_getline()
  cat-file: read batch stream with strbuf_getline()
  transport-helper: read helper response with strbuf_getline()
  clone/sha1_file: read info/alternates with strbuf_getline()
  remote.c: read $GIT_DIR/remotes/* with strbuf_getline()
  ident.c: read /etc/mailname with strbuf_getline()
  rev-parse: read parseopt spec with strbuf_getline()
  revision: read --stdin with strbuf_getline()
  hash-object: read --stdin-paths with strbuf_getline()
