21309bc6d7 Error on bytecodes longer than 0xFFFF (fix #269) 
This lets us use uint16_t for the program counter. JVM
languages have the same limit on method size so it is a
reasonable limit.

4a316fbb5a fix errors flagged by clang static analyzer 
builtin.c: bug - free of uninitialized jv
compile.c: missing assertion
jq_test.c: buggy logic / unreachable code
jv.c: missing assertion
jv_alloc.c: false positive - intentional read of uninitialized memory
jv_file.c: dead code

`. as [[[$i]], {a: $j}] | ...`
`foreach . as [$i, $j, $k] (...)`
`reduce . as {a: $i, b: $j} (...)`

ae7f8d6ab9 Further module system revamp (fix #659) 
To import a module now use:

    # Import module.jq file:
    import "relative/path/to/module" as foo;

    # Use the module's defs as foo::<def-name>

To import a JSON file:

    # Read file.json:
    import "relative/path/to/file" as $foo;
    #
    # Use as $foo::foo

Using `-L` now drops the builtin library path and appends the requested
path to the empty array (or the result of an earlier `-L`).

Support for the `$JQ_LIBRARY_PATH` environment variable has been
removed.

7dc34b92af Add label $name | EXP; fix break 
This is to fix the problem where `break` is dynamic, not lexical.

With this it should be possible to do this sort of thing:

    label $break | inputs | if ... then $break|error else . end

This is a backwards-incompatible change for master, but the previous
`break` hadn't shipped yet.

Still needed:

 - testing

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

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

47e015e946 Make a few constant globals actually const. 
This means the .data and .bss sections are empty, a good thing
in a shared library (see #98).

c013b557a2 Change APPEND opcode to directly modify a variable.

d5fdf70434 Refactor assignment. 
New version is much more elegant and probably slower. Uses
library functions implemented in jq rather than dedicated opcodes.

616e8f9924 Refactor function argument passing into what it always should have been. 
Most visible change is that error messages when a function is called
with the wrong number of arguments are much better.
