Nicolas Williams 5bfb9781f7 Add Streaming parser (--stream) 
Streaming means that outputs are produced as soon as possible.  With the
`foreach` syntax one can write programs which reduce portions of the
streaming parse of a large input (reduce into proper JSON values, for
example), and discard the rest, processing incrementally.

This:

    $ jq -c --stream .

should produce the same output as this:

    $ jq -c '. as $dot | path(..) as $p | $dot | getpath($p) | [$p,.]'

The output of `jq --stream .` should be a sequence of`[[<path>],<leaf>]`
and `[[<path>]]` values.  The latter indicate that the array/object at
that path ended.

Scalars and empty arrays and objects are leaf values for this purpose.

For example, a truncated input produces a path as soon as possible, then
later the error:

    $ printf '[0,\n'|./jq -c --stream .
    [[0],0]
    parse error: Unfinished JSON term at EOF at line 3, column 0
    $

Nicolas Williams e51e916e31 Fix foreach non-progation of errors 
Errors were being re-propagated as "break".

Also add `error/0` builtin, which made this fix easier.

Zhiming Wang a5e9086676 Let @uri produce uppercase hexadecimal digits... 
instead of lowercase ones.

According to RFC 3986,

   The uppercase hexadecimal digits 'A' through 'F' are equivalent to
   the lowercase digits 'a' through 'f', respectively.  If two URIs
   differ only in the case of hexadecimal digits used in percent-encoded
   octets, they are equivalent.  For consistency, URI producers and
   normalizers should use uppercase hexadecimal digits for all percent-
   encodings.

See https://github.com/stedolan/jq/issues/451 for details.

Test suite and manual are also updated to reflect this change.

William Langford 8ff935c01a Added regex support as per issue #164. 
jq now depends on oniguruma for regex support.
Modified configure.ac accordingly.

Added valgrind suppression file for oniguruma to prevent one-time and bounded
leaks from causing tests to fail.
