rmacklem d25c98bbc4 Make MAXBCACHEBUF a tunable called vfs.maxbcachebuf. ...

By making MAXBCACHEBUF a tunable, it can be increased to allow for
larger read/write data sizes for the NFS client.
The tunable is limited to MAXPHYS, which is currently 128K.
Making MAXPHYS a tunable or increasing its value is being discussed,
since it would be nice to support a read/write data size of 1Mbyte
for the NFS client when mounting the AmazonEFS file service.
