Junio C Hamano	4ae6670444	stream filter: add "no more input" to the filters Some filters may need to buffer the input and look-ahead inside it to decide what to output, and they may consume more than zero bytes of input and still not produce any output. After feeding all the input, pass NULL as input as keep calling stream_filter() to let such filters know there is no more input coming, and it is time for them to produce the remaining output based on the buffered input.

stream filter: add "no more input" to the filters

Some filters may need to buffer the input and look-ahead inside it
to decide what to output, and they may consume more than zero bytes
of input and still not produce any output. After feeding all the
input, pass NULL as input as keep calling stream_filter() to let
such filters know there is no more input coming, and it is time for
them to produce the remaining output based on the buffered input.

Add streaming filter API

This introduces an API to plug custom filters to an input stream.

The caller gets get_stream_filter("path") to obtain an appropriate
filter for the path, and then uses it when opening an input stream
via open_istream().  After that, the caller can read from the stream
with read_istream(), and close it with close_istream(), just like an
unfiltered stream.

This only adds a "null" filter that is a pass-thru filter, but later
changes can add LF-to-CRLF and other filters, and the callers of the
streaming API do not have to change.

convert.h: move declarations for conversion from cache.h

Before adding the streaming filter API to the conversion layer,
move the existing declarations related to the conversion to its
own header file.
