Emulate mremap(2) by returning ENOMEM for now. This should be sufficient for

realloc(3) and other uses. From Matthias Scheler in PR 3920.

Signal error when getting a 64 bit offset cookie that can't be stored
...
in 32 bits. Provide an error message to the user, and return EINVAL.
Also, pay attention to the EOF flag from VOP_READDIR. Correct a
misspell in a panic message.

Fix "missing entries" bug when reading large directories: When reading a
...
directory and running out of space in the dest buffer, off should point to the
current entry (which was not saved) and not to the next.
I discovered this bug using linux and SunOS emulation over NFS, but seems to
affect other emulations as well.

Changes to the sudio system:
...
- It is now possible to handle devices that want "looping" DMA,
e.g. the SoundBlaster correctly. The WSS and SB drivers use this.
To do this several new methods were introduced in audio_hw_if.
- Different silence handling (forced by previous change).
- The audio driver can now be mmap()-ed, but due to problems in
the VM system only for writing for now.
- The OSS (Linux) audio emulation takes advantage of some of the
new features.
