    i386: specialize `copyinmsg' and `copyoutmsg'
    
    Previously, `copyinmsg' was the same function as `copyin'.  The former
    is for messages, and the size of messages is a multiple of four.
    Likewise for `copyoutmsg'.
    
    Provide a specialized version of both functions.  This shaves off a
    couple of instructions and improves our IPC performance.
    
    * i386/i386/locore.S (copyinmsg): New function.
    (copyoutmsg): New function.

    i386: drop needless instruction from `copyout'
    
    * i386/i386/locore.S (copyout): Do not needlessly copy length to %eax
    first.

    kern: improve assert
    
    Use the ternary operator to implement `assert' like it is done in the
    glibc.  The glibcs changelog does not mention the rationale behind
    this change, but doing the same seems to improve our IPC performance.
    
    * kern/assert.h (assert): Define macro using the ternary operator.

    linux: fix compiler warning
    
    If the loop above completes at least one iteration, `i' will be larger
    than zero.
    
    * linux/dev/glue/block.c (rdwr_full): Add assertion to appease the
    compiler.
