dyncall:
  o new, portable aggregate-by-value argument interface
  o aggregate-by-value (struct, union) support for x64 (win and sysv; thanks Raphael Luba!)
  o new aggregate description interface DCaggr replacing stale DCstruct (latter had shortcomings, was
    mostly unused as it lacked stable implementations, didn't handle unions, ...)
  o new calling convention modes for thiscalls (platform agnostic DC_CALL_C_DEFAULT_THIS, as well as
    DC_CALL_C_X64_{WIN64,SYSV}_THIS (needed to handle C++ ABI rules for returning aggregates by value)
  o new signature character for platform agnostic thiscalls ('*' / DC_SIGCHAR_CC_THISCALL)
  o dcCallF(), dcVCallF(), dcArgF() and dcVArgF() don't implicitly call dcReset()
    anymore, which was unflexible (breaking change)

  o windows/x64/masm directives added to specify how stack unwinds (help for
    debuggers, exception handling, etc.; thanks Raphael Luba)

    the MSVC runtime (e.g. ReactOS' MinGW based RosBE)

  o added many more usage examples to man pages
  o replaced API description in manual with references to the manpages, to
    avoid duplication and keeping things in sync

  o support for soft-float MIPS o32 & n64 (big- and little-endian, each)

    paths to random libraries under some circumstances, instead of returning an error)
  o support for dlGetLibraryPath() on glibc platforms with glibc vesions <= 2.3.3
  o dlGetLibraryPath() now accepts NULL as argument to return path to executable

dynload:
  o major reliability/stability fixes for Mach-O dlSyms* functions to (thanks Stéphane Mons for help):
    better handle loading dylibs by symlink, relative path, random casing, etc.
    fixes to symbol name lookups that used wrong offsets before
    64-bit platform fixes (was broken on x64 and never supported on others)
  o allowing Mach-O dlSyms* lib to be used standalone (consistent with ELF and PE impls now)
  o simplifications of implemention on Darwin, sharing parts with *nix implementation

    return symbol names as they would appear in C code, instead of the raw ones in object files
  o added new function dlGetLibraryPath, allowing lookups of path to library via handle
general:
  o assembly code now built by explicitily asking for non-execstack, for safer/easier integration
    into other projects/builds, where needed; needed b/c of questionable default behaviours of some
    toolchains (thanks Thorsten Behrens for report and analysis)
