4663ac0fe7 split debug_assert into ENSURE and ASSERT as discussed in a previous meeting.
the old debug_assert always ran and tested the expression, which slows
down release builds. wrapping them in #ifndef NDEBUG is clumsy. the new
ASSERT behaves like assert and ENSURE like the old debug_assert. Let's
change any time-critical but not-super-important ENSURE to ASSERT to
speed up release builds. (already done in bits.h and unique_range.h)

This was SVN commit r9362.

2374caac3e major refactor of file/io and alignment code. requires update-workspaces
. completely rewrite waio - use IOCP, add several hardcore
optimizations. now outperforms the
  AS SSD and ATTO benchmarks when writing
. refactor file interface - use LIO_READ instead of 'r', allow access to
file descriptor.
. completely rewrite the IO wrapper. now much more simple, less CPU
overhead, adds
  support for pre-issue/post-completion hooks and preallocation.
  io::Run defaults to simple synchronous IO; use io::Parameters to get
asynchronous.
. add alignment.h with constants and Align() function template (more
efficient than
  round_up for compile-time constants)
. add UniqueRange - similar to C++0x unique_ptr (emulated for C++03),
plus a
  built-in size. avoids expensive thread-safe reference counting in
shared_ptr.

cleanup:
- move fat_time functions into archive_zip
- remove no longer needed io_align and block_cache
- reduce dependencies in sysdep/compiler (move parts to
code_annotation.h)
- move IOCP into separate file (reused by waio)

This was SVN commit r9350.
