vlib: process startup config exec scripts line by line

This fixes long standing annoyance that CLIs with optional args cannot
be executed from file, as they cannot distinguish between valid optional
args and next line in the file.

Multiline statements can be provided simply by using backslash before \n.
Also comments are supported - everything after # is ignored up to the
end of the line.

Example:

 # multiline cli using backslash
show version \
       verbose # end of line comment

packet-generator new { \
   name x \
   limit 5 \
   # comment inside cmultiline cli \
   size 128-128 \
   interface local0 \
   node null-node \
   data { \
       incrementing 30 \
   } \
}

Type: fix
