DMD 2.071 compatibility, std.stream now part of D:YAML

• DMD 2.071 fixes by Martin Nowak.
• std.stream thanks to burner's work.
  This should be a temporary fix until std.stream is completely replaced by pre-allocated memory or ranges;
  that may take a while as I currently lack the time to put serious work into D:YAML.

DMD 2.068 compatibility

Fixed compilation with DMD 2.068

Had to use a lot of @trusted as std.variant.VariantN is again less safe.
Will need to change that back once it gets safer, or at least isolate
code using it so that half of Node API doesn't need to be @trusted.

Bugfixes and DMD compatibility

• Documentation is now generated by harbored-mod
• Node constructors nothrow where possible
• Compatible with DMD 2.067

0.4.6: 0.4.5 with a fixed package.json to get code.dlang.org to work.

v0.4.6

Fixed a package.json bug to allow code.dlang.org to detect 0.4.5.

v0.5.0

This release brings decreased GC usage thanks to slices, improved performance, a few minor features, and some
breaking changes.

Breaking changes

As many people have been using D:YAML from git master since the 0.4 release, each change
is prefixed by the year the change was introduced.

• 2014 The cdc.d build script has been removed; dub is now the only 'official'
  way to build D:YAML.
• 2014 Broke compatibility with all DMD versions before 2.066
• 2014 Loader API depending on std.stream is now deprecated and will be
  removed in the next release.
• 2014 Loader.fromString(string) is now deprecated and replaced by
  Loader.fromString(char[]), which will reuse and overwrite the input during
  parsing. The string overload will be removed in the next release.
• 2012 Values in D:YAML are less 'dynamic-typed'. E.g. removing "42" won't
  also remove 42. Such automatic conversion still happens e.g. in a foreach
  over a mapping with a string key. The Node.as() method has a template
  parameter to disable automatic conversion from strings to other types.

API improvements

• Loader is now, by default, constructed from a non-const buffer containing YAML
  data instead of a std.stream.Stream. D:YAML reuses and overwrites this buffer to
  minimize memory allocations during parsing. Convenience API such as the Loader
  constructor from a filename is unchanged although it loads the file to a buffer
  internally.
• Node.contains() method to check if a YAML sequence/mapping contains specified
  value (as opposed to a key).
• Node.containsKey() method to check if a YAML mapping contains specified key.
• Node.isNull() property.
• Node operator in analogous to associative array in.
• Loader.fromString() method as a quick wrapper to parse YAML from a string.
• dyaml.hacks module for potentially useful things YAML specification doesn't allow.
• Most of the API is @safe or at least @trusted. Also pure and nothrow
  where possible.
• User-defined constructors can now also construct builtin YAML types.
• Input is now validated at Loader construction to detect invalid UTF sequences early
  and to minimize internal exception handling during parsing.

Other improvements

• D:YAML now works with a UTF-8 buffer internally. This decreases memory usage for UTF-8
  input, and UTF-32 inputs can be encoded into UTF-8 in-place without allocating.
  UTF-16 inputs still need an allocation. This also gets rid of all dchar[]->char[]
  conversions which were a significant source of GC allocations.
• Various optimizations in Reader/Scanner, especially for mostly-ASCII files
  containing plain scalars (most common YAML files). Measured speedup of ~80% when
  parsing mostly-ASCII
  files, slowdown of ~12% for mostly non-ASCII files (all tested files were UTF-8).
• Less GC usage during YAML node construction.
• Scanner is now mostly @nogc; it never allocates memory for token values, using
  slices into the input buffer instead.
• Custom, @nogc UTF decoding/encoding code based on std.utf to enable more use
  of @nogc in D:YAML internals and to improve performance.
• Less memory allocations during scanning in general, including manual allocations.
• Default Constructor/Resolver are now only constructed if the user doesn't
  specify their own.
• Replaced std.stream.EndianStream with
  tinyendian.
• D:YAML is now a DUB package.
• Removed static data structures such as default Constructor and Resolver.
• Compile-time checks for size of data structures that should be small.
• Better error messages.
• Various refactoring changes, using more 'modern' D features, better tests.
• Updated documentation, examples to reflect changes in 0.5.
• Updated the yaml_bench example/tool with options to keep the input file in memory
  instead of reloading it for repeated parses, and to only benchmark scanning time
  instead of the entire parser.
• The yaml_gen example/tool can now generate strings from user-specified alphabets
  which may contain non-ASCII characters.

Bugfixes

• Fixed mappings longer than 65535 lines.
• Removed a lot of in parameters that were used due to a misunderstanding of what
  in is supposed to do.
• Fixed real emitting.
• Fixed 32bit compilation (again).
• Various small bugfixes.

v0.4.5 - a snapshot of 'old' DMD 2.065-compatible D:YAML before 0.5

This is not a 'proper' release, hence the weird version name.

This version mainly exists for DMD 2.065 compatibility as v0.5 will require DMD 2.066. As this is just a snapshot of recent state of the git repo, it includes new features since v0.4. A proper changelog will be included with v0.5
