+ * Shared error messages: declarations and macros
+ *
+ * Error messages are accessed through macros with fine-grained, explicit
+ * error message distinctions. Concrete error messages are selected by the
+ * macros and multiple macros can map to the same concrete string to save
+ * on code footprint. This allows flexible footprint/verbosity tuning with
+ * minimal code impact. There are a few limitations to this approach:
+ * (1) switching between plain messages and format strings doesn't work
+ * conveniently, and (2) conditional strings are a bit awkward to handle.
+ *
+ * Because format strings behave differently in the call site (they need to
+ * be followed by format arguments), they have a special prefix (DUK_STR_FMT_
+ * and duk_str_fmt_).
+ *
+ * On some compilers using explicit shared strings is preferable; on others
+ * it may be better to use straight literals because the compiler will combine
+ * them anyway, and such strings won't end up unnecessarily in a symbol table.

+ * Tagged type definition (duk_tval) and accessor macros.
+ *
+ * Access all fields through the accessor macros, as the representation
+ * is quite tricky.
+ *
+ * There are two packed type alternatives: an 8-byte representation
+ * based on an IEEE double (preferred for compactness), and a 12-byte
+ * representation (portability). The latter is needed also in e.g.
+ * 64-bit environments (it usually pads to 16 bytes per value).
+ *
+ * Selecting the tagged type format involves many trade-offs (memory
+ * use, size and performance of generated code, portability, etc),
+ * see doc/types.txt for a detailed discussion (especially of how the
+ * IEEE double format is used to pack tagged values).
+ *
+ * NB: because macro arguments are often expressions, macros should
+ * avoid evaluating their argument more than once.

+ * abandoned and moved to the 'entry part'.
+ *
+ * 3. An optional 'hash part' is used to optimize lookups of the entry
+ * part; it is used only for objects with sufficiently many properties
+ * and can be abandoned without loss of information.
+ *
+ * These three conceptual parts are stored in a single memory allocated area.
+ * This minimizes memory allocation overhead but also means that all three
+ * parts are resized together, and makes property access a bit complicated.

+ * e_size * sizeof(duk_hstring *) bytes of entry keys (e_next gc reachable)
+ * e_size * sizeof(duk_uint8_t) + pad bytes of entry flags (e_next gc reachable)
+ * a_size * sizeof(duk_tval) bytes of (opt) array values (plain only) (all gc reachable)
+ * h_size * sizeof(duk_uint32_t) bytes of (opt) hash indexes to entries (e_size),
+ * 0xffffffffUL = unused, 0xfffffffeUL = deleted
+ *
+ * Layout 3 (DUK_USE_HOBJECT_LAYOUT_3):
+ *
+ * e_size * sizeof(duk_propvalue) bytes of entry values (e_next gc reachable)
+ * a_size * sizeof(duk_tval) bytes of (opt) array values (plain only) (all gc reachable)

+ * 0xffffffffUL = unused, 0xfffffffeUL = deleted
+ * e_size * sizeof(duk_uint8_t) bytes of entry flags (e_next gc reachable)
+ *
+ * In layout 1, the 'e_next' count is rounded to 4 or 8 on platforms
+ * requiring 4 or 8 byte alignment. This ensures proper alignment
+ * for the entries, at the cost of memory footprint. However, it's
+ * probably preferable to use another layout on such platforms instead.
+ *
+ * In layout 2, the key and value parts are swapped to avoid padding
+ * the key array on platforms requiring alignment by 8. The flags part
+ * is padded to get alignment for array entries. The 'e_next' count does
+ * not need to be rounded as in layout 1.
+ *
+ * In layout 3, entry values and array values are always aligned properly,
+ * and assuming pointers are at most 8 bytes, so are the entry keys. Hash
+ * indices will be properly aligned (assuming pointers are at least 4 bytes).
+ * Finally, flags don't need additional alignment. This layout provides
+ * compact allocations without padding (even on platforms with alignment
+ * requirements) at the cost of a bit slower lookups.
+ *
+ * Objects with few keys don't have a hash index; keys are looked up linearly,
+ * which is cache efficient because the keys are consecutive. Larger objects
+ * have a hash index part which contains integer indexes to the entries part.
+ *
+ * A single allocation reduces memory allocation overhead but requires more
+ * work when any part needs to be resized. A sliced allocation for entries
+ * makes linear key matching faster on most platforms (more locality) and
+ * skimps on flags size (which would be followed by 3 bytes of padding in
+ * most architectures if entries were placed in a struct).
+ *
+ * 'props' also contains internal properties distinguished with a non-BMP
+ * prefix. Often used properties should be placed early in 'props' whenever
+ * possible to make accessing them as fast a possible.
