Refactor the filter.<driver>.process code into a separate sub-process
module that can be used to reduce the cost of starting up a sub-process
for multiple commands. It does this by keeping the external process
running and processing all commands by communicating over standard input
and standard output using the packet format (pkt-line) based protocol.
Full documentation is in Documentation/technical/api-sub-process.txt.
This code is refactored from:
Commit edcc85814c ("convert: add filter.<driver>.process option", 2016-10-16)
keeps the external process running and processes all commands
Ben Peart (8):
pkt-line: add packet_read_line_gently()
convert: move packet_write_list() into pkt-line as packet_writel()
convert: Split start_multi_file_filter into two separate functions
convert: Separate generic structures and variables from the filter
specific ones
convert: Update generic functions to only use generic data structures
convert: rename reusable sub-process functions
sub-process: move sub-process functions into separate files
convert: Update subprocess_read_status to not die on EOF
