Remove libkern, leave just header.

Browse source 
Boot stuff dependencies from NetBSD.

Patch by Antoine Leca. Relocated to src/sys.

The port is using the same libminc.a as usual MINIX services (and does
not use NetBSD libkern); the headers imported from NetBSD sys/ tree
have been kept to a minimum (still numbers higher than 30 though.)

Note the peculiar way to use libraries (libsa, libi386, etc.): the
source code is shared, but each component builds its own copy of the
library, with its own set of preprocessor defines.

/*
* This macro is definitely strange. It exists purely to
* allow the _COPYS macro to be reused, but because it
* requires this long attempt to explain it, I'm starting
* to doubt the value of that.
*
* Part of the expansion of the _COPYS macro below are loops
* that copy four words or one word at a time, performing shifts
* to get data to line up correctly in the destination buffer.
*
* The _COPYS macro is used when copying backwards, as well
* as forwards. The 4-word loop always loads into %t1, %t2, %t3,
* and %t4 in that order. This means that when copying forward,
* %t1 will have the word from the lowest address, and %t4 will
* have the word from the highest address. When copying
* backwards, the opposite is true.
*
* The shift instructions need pairs of registers with adjacent
* words, with the register containing the word from the lowest
* address *always* coming first. It is this assymetry that
* gives rise to this macro - depending on which direction
* we're copying in, these ordered pairs are different.
*
* Fortunately, we can compute those register numbers at compile
* time, and assemble them manually into a shift instruction.
* That's what this macro does.
*
* This macro takes two arguments. n ranges from 0 to 3 and
* is the "shift number", i.e., n = 0 means we're doing the
* shift for what will be the first store.
*
* m is the displacement multiplier from the _COPYS macro call.
* This is 1 for a forward copy and -1 for a backwards copy.
* So, the ((m + 1) / 2) term yields 0 for a backwards copy and
* 1 for a forward copy, and the ((m - 1) / 2) term yields
* 0 for a forward copy, and -1 for a backwards copy.
* These terms are used to discriminate the register computations
* below.
*
* When copying forward, then, the first register used with
* the first vshd will be 19 + (3 - ((0 - 1) & 3)), or %t4,
* which matches _COPYS' requirement that the word last loaded
* be in %t4. The first register used for the second vshd
* will then "wrap" around to 19 + (3 - ((1 - 1) & 3)), or %t1.
* And so on to %t2 and %t3.
*
* When copying forward, the second register used with the first
* vshd will be (19 + (3 - ((n + 0) & 3)), or %t1. It will
* continue to be %t2, then %t3, and finally %t4.
*
* When copying backwards, the values for the first and second
* register for each vshd are reversed from the forwards case.
* (Symmetry reclaimed!) Proving this is "left as an exercise
* for the reader" (remember the different discriminating values!)
