You can now pass a boolean "allow_exceptions" to the parse functions. If it is false, no exceptions are thrown in case of a parse error. Instead, parsing is stopped at the first error and a JSON value of type "discarded" (check with is_discarded()) is returned.

C++ overload resolution/list initialization rules are hard.

- You can now pass a reference to a vector to the to_cbor and to_msgpack functions. The output will be written (appended) to the vector. #476

- You can now pass an output stream with uint8_t character type to the to_cbor and to_msgpack functions. #477

- You can now read from uint8_t */size in the to_cbor and to_msgpack functions. An input adapter will be created from this pair, so you need to use braces. #478

std::initializer_list does not own the temporaries created in
its initialization. Therefore, storing it in an independent
stack variable is unsafe.

We now rely on implicit conversions to an input_adapter object in the parse/accept functions.

Internally, the parser now writes its result into a JSON value provided as a reference. To be usable, the public interfaces need to be extended.

A complete rewrite of the string escape function. It now provides codepoint-to-\uxxxx escaping. Invalid UTF-8 byte sequences are not escaped, but copied as-is. I haven’t spent much time optimizing the code - but the library now agrees with Python on every single Unicode character’s escaping (see file test/data/json_nlohmann_tests/all_unicode_ascii.json).

Other minor changes: replaced "size_t" by "std::size_t"

avoid bloat caused by <iostream> and std::cout and friends in apps where
iostream are not used.

It makes no sense to have this special exception. Instead of throwing when an input adapter is created, it is better to detect a parse error in later usage when an EOF is "read" unexpectedly.

I have no idea why this test has been removed in the first place.

Travis aborts tests if they do not produce output for 10 minutes. This commit shall fix this.
