2017-06-08COMMON: Take immutable reference in SpanOwner copy assignmentColin Snover
Thanks again to @waltervn.
2017-06-08COMMON: Make SpanOwner copy assignment make a copy of the owned SpanColin Snover
To move data from one SpanOwner to another, use `moveFrom`. Thanks @waltervn for pointing out the problem.
2017-03-30COMMON: Reduce maximum Span size to 4GiBColin Snover
Until C++11 (which introduces the z and t length modifiers), there is no consistent way to print size_t and ptrdiff_t types using printf formatting across 32-bit, LLP64, and LP64 architectures without using a cumbersome macro to select the appropriate length modifier for the target architecture. Since ScummVM engines currently need to support 32-bit targets, there is no reason at the moment to support any larger memory sizes in Span anyway. Span error output is also updated in this commit to reflect that index values are unsigned.

2017-02-05GUI: Add three new options for volume slider controlsColin Snover
GUIO_NOSPEECHVOLUME can be used for games that allow toggling of speech but do not provide the ability for users to control speech volume. GUIO_LINKMUSICTOSFX and GUI_LINKSPEECHTOSFX can be used for games that allow control of music, sfx, and speech in combinations, like games that provide control of digital audio separately from MIDI, or games that only control all three audio types through a single volume control.

2017-01-08COMMON: Fix GCC 4 shadow warnings in SpanColin Snover
2017-01-08COMMON: Simplify Span codeColin Snover
Implicitly generated constructors can be used instead of explicit constructors, which reduces the amount of necessary boilerplate. Long lists of identical typedefs to the superclass are now defined using a macro. data() const now returns a pointer to data that matches the value_type of the data, instead of forcing the data to be const. This better matches the intent of the Span class, which provides a view into data, rather than being a container that holds data.
2017-01-08COMMON: Restrict use of data access helpersColin Snover
The data access helpers as written are effectively little-endian when reading from spans with value_types larger than the size of the requested data (e.g. more than 1 byte for getting a char, more than 2 bytes for getting a uint16, etc.). For now, restrict use of these methods at compile time until someone actually needs to read memory that way.

2017-01-08COMMON: Add Span to common libraryColin Snover
Span is roughly modelled on the GSL span<T> type, and is intended to replace direct access to raw pointers -- especially pointers that are passed to functions along with a separate size parameter. It provides low-cost bounds-checked reads and writes, as well as convenience functions for reading common values (integers of varying endianness, strings, etc.). While similar to MemoryReadStream in purpose, Span is superior in cases where memory is writable, where memory is accessed randomly rather than sequentially, or where any invalid access should be treated as an unrecoverable error. It should also be more efficient than a MemoryReadStream because it is implemented using CRTP, so there is no runtime overhead from dynamic dispatch. NamedSpan is an extension of Span which provides enhanced debugging information when out-of-bounds memory accesses occur. It allows programmers to name the memory span at construction time, and it also tracks the offsets of subspans so that the absolute byte offset of the original memory can be provided in the error message if an out-of-bounds access occurs. SpanOwner is similar to ScopedPtr but has awareness of the design of Span objects, so allows the memory pointed to by the Span object inside the SpanOwner to be freed when the SpanOwner is freed without requiring holding a separate pointer to the start of memory. It also provides some copy semantics, so unlike a ScopedPtr, SpanOwners can be held by objects in movable containers like Common::Array -- but note that because there are no move semantics in C++98, this means that a new, complete memory copy of the pointed-to data will be created, rather than just a new Span pointing to the same block of memory, when a container holding a SpanOwner expands.
2017-01-08COMMON: Add type traits to common libraryColin Snover
Type traits allow conditional selection and manipulation of types during compilation.
2017-01-05COMMON: Add strnlen for safer C string length readsColin Snover
This API is intended for use in cases where C strings come from untrusted sources like game files, where malformed data missing the null terminator would cause strlen to read out of bounds.

2016-10-30COMMON: Fix GCC Warning in JSON Parser.D G Turner
The emitted warning is "ISO C++98 does not support the ‘%lg’ gnu_printf format [-Wformat=]". Though "%lg" is required for *scanf functions to indicate the field size, it is not required for *printf functions which use "%g" instead.
2016-10-29COMMON: Add referencing and destruction of the OSDMessageQueue instanceThierry Crozat
Registering the OSDMessageQueue instance as an event source is now done right after the event manager is initialised. This ensures that it is created in a sensible place and not for example in another thread). Also registering the event source is moved to a separate function instead of being in the constructor to remove any issue in case some code tries to display a OSD Message very early on (the instance would be created then, but it would be registered as an event source later).
2016-10-29COMMON: Add OSDMessageQueue singletonThierry Crozat
This class can be used to get messages to display on the OSD from any thread. Those messages are then passed to the backend in the graphic thread.
