Add .data8 for 8-byte literal integers to the assembler.
...
This takes literal integers, not expressions, because each machine
defines its own valu_t for expressions, but valu_t can be too narrow
for an 8-byte integer, and I don't want to change all the machines to
use a wider valu_t. Instead, change how the assembler parses literal
integers. Remove the NUMBER token and add a NUMBER8 token for an
int64_t. The new .data8 pseudo emits all 8 bytes of the int64_t;
expressions narrow the int64_t to a valu_t. Don't add any checks for
integer overflow; expressions and .data* pseudos continue to ignore
overflow when a number is too wide.
This commit requires int64_t and uint64_t in the C compiler to build
the assembler. The ACK's own C compiler doesn't have these.
For the assembler's temporary file, add NUMBER4 to store 4-byte
integers. NUMBER4 acts like NUMBER[0-3] and only stores a
non-negative integer. Each negative integer now takes 8 bytes (up
from 4) in the temporary file.
Move the `\fI` and `\fP` in the uni_ass(6) manual, so the square
brackets in `thing [, thing]*` are not italic. This looks nicer in my
terminal, where italic text is underlined.

Include more headers to declare functions.
...
This causes clang to give fewer warnings of implicit declarations of
functions.
In mach/pdp/cv/cv.c, rename wr_int2() to cv_int2() because it
conflicts with wr_int2() in <object.h>.
In util/ack, rename F_OK to F_TRANSFORM because it conflicts with F_OK
for access() in <unistd.h>.
