4cd777712b Enhance handling of circular references 
It's now an error to try to add an object or array to itself. The
encoder checks for circular references and fails with an error status
if one is detected.

951d091f07 Make integer, real and string mutable 
Added functions:

  json_string_set
  json_integer_set
  json_real_set

While at it, clarify the documentation and parameter naming of
json_{string,integer,real}_value() a bit.

743af38e7f Use unsigned long instead of uint32_t 
Some day we will have ANSI C compatibility... This change doesn't make
the API backwards incompatible because uint32_t was only used in flags
to json_dump*() and the flags are meant to be used only by ORing
constants and macro output, and actually currently only JSON_INDENT
can be used.

0f62dac627 load: Handle EOF correctly 
In stream_get(), EOF never got it to stream->buffer and because of
this, stream_unget() failed on some situations. This patch makes
stream_get() handle EOF just like any other byte.

As a "side effect", lex_scan_string() now needs to unget the EOF, or
otherwise it ends up in error message on premature end of input.

7ee974e91c Don't perform reference counting on true, false and null 
This makes their constructors thread safe. A special reference count
-1 is used to test whether to perform reference counting on a value or
not.

234ee47281 Better argument validation 
All pointer arguments are now tested for NULL. json_string() now also
tests that strdup() succeeds. This is to ensure that no NULL values
end up in data structures.

Also desribe the different sources of errors in documentation.

9611780907 dump: Optimize indenting 
Don't alloca() a whitespace buffer and fill it with spaces in each
call to dump_indent. Instead, use a static whitespace buffer.

As a bonus, this saves the use of poorly portable alloca().

df307f1bc3 Report errors from lexical and stream level in parser 
Before, only the syntax level (parse_*) was able to set the error
string. This patch fixes the situation so that lexical (lex_*) and
stream (stream_*) levels can report detailed error messages.

Also, instead of 0, EOF is now returned by stream on error.

b1fe723a7f Fix json_loadf and json_loadfd with empty input 
Nothing was appended to strbuffer, so the buffer was left empty. An
empty strbuffer is not an empty string but NULL, so the result was a
segfault.

This patch fixes the problem by initializing strbuffer to an empty
string.
