The .de1 instructions is a GNU extension not found in traditional roff and
not even in old groff, defined as "define a macro that will be executed with
traditional roff compatibility mode switched off during macro execution".
Since we ran into it in the wild, we have been parsing and ignoring it for
a long time. Now that we have proper .de support, we can as well use the
contents, even though we don't implement compatibility mode at all.

such that arguments can contain blank characters.
Also support escaping of quote characters by doubling them.
For example, the argument "a""b c." resolves to: a"b c.

This fixes various Xenocara manuals.
Do not define your own macros in new manuals, though:
this code exists purely to cope with existing and old stuff.
Like in both traditional and GNU roff, the .de and .ds (define string)
roff instructions share the same string table, so one can abuse strings
as macros and vice versa. This implementation supports multi-line
user-defined macros and user-defined macros taking up to 9 arguments.
Project started near the end of p2k10, now mature for production,
but there is still room for future improvements in various respects.

enabled by option FPUEMUL.
This is pretty straightforward, except for conditional branch on FPU condition
codes emulation (bc1f/bc1fl/bc1t/bc1tl instructions): unlike most
RISC-with-delay-slots designs (m88k, sparc), the branch pipeline is not exposed
to the kernel on Mips, therefore we can not resume a branch without losing the
delay slot instruction.
Some other operating systems work around this issue by emulating the delay
slot instruction, but this is error-prone (and requires the kernel code to
be aware of all supported instructions of the processor it is currently running
on), some use dedicated breakpoints to single-step through the delay slot and
then resume the branch as expected, but this causes a lot of copy-on-write
allocations.
This code chooses a third path, of copying the delay slot instructions to run toa special `magic' page, followed by a special trap instruction to give control
back to the kernel. This makes sure the instruction will actually be run by the
processor, and that no more than one page per process is wasted, regardless of
the number of branches to emulate.
Tested on octeon (big-endian) by syuu@ and on loongson (little-endian) by me.
Note that enabling option FPUEMUL in the kernel will completely disable the
hardware FPU, if there is one; there is currently no way to build a kernel
supporting both hardware and software FPU, and there is no reason to change
this until there is a strong need to support both.

fix aliases functions to use a buffer that's appropriate, preventing a
