Qt defines emit as an empty macro, so a Qt header included before
json_view.hpp broke the lambda's declaration (see #5865). The slots
variables in the image tests are renamed as well.

The review of #5620 renamed document_data's tape/tape_size/tape_cap to
nodes/node_count/node_capacity and made the decode arena a
std::vector<char>; adapt the code of this change to it.

json_view.hpp uses std::istream and std::ostream itself, but IWYU sees
them through the exported json.hpp and asked to remove both includes,
which fails ci_single_binaries (single_json_view).

Develop's #5800 made basic_json report a JSON pointer array index such as
"/a" as parse_error.109 instead of out_of_range.404, as longer ones were;
the view's array_index() follows, with "-" and the empty token still
unresolved.

memcpy() must not be passed a null pointer even for zero bytes, which
arena_run() did for an empty run while the arena was still empty
(ci_test_clang_sanitizer: "null pointer passed as argument 1" in
builder.hpp). Only the slow path can see such a run.

Qt defines emit as an empty macro, so a Qt header included before
json_view.hpp broke the declaration of the builder's emit(), see
issue #5865. It is now called push_node().

- inline_nodes is null when the document has no inline nodes, instead of
pointing past the end of the allocation; shrink_to_fit() no longer
passes it to memcpy() for an empty node array
- is_byte_char and is_wide_char use conjunction/disjunction, which
astyle leaves unspaced
- append_stream() uses (std::max) for the count read

Changes promised in the replies to the review of #5620:
- read() reuses the owned copy: a copied input (an rvalue byte container,
a stream, FILE*, wide characters, an iterator range) is appended to the
cleared owned buffer instead of a fresh std::string being move-assigned
over it. A moved-in std::string still replaces it.
- The error replay runs the library parser with a SAX handler that stores
nothing and throws the reported exception, instead of
BasicJsonType::parse(), which built a DOM up to the error.
- Pointers to and arrays of wide characters, and FILE*, take the input
adapter path (converted to UTF-8 into an owned buffer) instead of
failing a static_assert. Wide pointers are NUL-terminated.
- Streams are read in blocks through rdbuf() into the buffer, instead of
character by character through the input adapter; eofbit is set at the
end, as by the library's stream adapter.
- tape/tape_size/tape_cap are now nodes/node_count/node_capacity.
- The builder's members get descriptive, m_-prefixed names.
- The shallow frame stack is a std::array (in a wrapper with a
user-provided constructor: -Weffc++ wants the member initialized, and
value-initializing the 64 frames costs up to 30 % on small documents).
- The value dispatch macro has no NEXT parameter; the switch is left with
break, and the macro is undefined after its last use.
- literal() and digits_exceed() deduce the length from the string literal;
each literal has one helper; the two `if (!is_float)` blocks are merged.
- arena_ensure() sits right before the writes; the decode arena is a
std::vector<char>.
- The builder records the deepest nesting, and materialize() sizes its
stack from it once (growing it only if a subtree is deeper).
- Comment fixes (hex4, slow_string, the NUL rule, put_utf8, 0 - m, the
arena resize, grow()) and formatting (macro backslashes, digit cases,
one power of ten per line, value_t assertion next to is_container()).
- build_with's template parameters follow the builder's order.
Greg's idea of keeping the source offset in `off` and the arena offset in
`next` for escaped strings was measured and not adopted: string access got
7-18 % slower with a select, and 3.5-18 % slower with a branch-free field
pick (Apple M-series, clang -O3), parsing was unchanged.
