rge: make rx_process_limit a sysctl tunable
The number of packets processed per interrupt was hardcoded to 16.
Add a per-interface sysctl dev.rge.%d.rx_process_limit tunable so
users can adjust this value at runtime.

rge.4: fix incorrect speed range in HARDWARE section
The HARDWARE section stated "PCIe 1GB to 1GB Ethernet devices"
which is incorrect. The RTL8125/8126/8127 chips support speeds
from 1Gbps to 10Gbps. Correct the range.

rge.4: note that the driver manages PHY directly
The rge(4) driver does not use the miibus(4) interface for PHY
management. Instead, it accesses PHY registers directly via the
chip's OCP (On-Chip Peripheral) bus. Document this in the
DESCRIPTION section.

realpath: Improve prev_len logic
* Save prev_len after having checked for and appended a trailing slash,
not before. This requires us to back up if we end up returning a
partial result, but previously we would sometimes return a partial
result with a trailing slash and sometimes without.
* Replace strlcat() with a faster strlcpy() since we know exactly how
far into the buffer we are.

m4: Stop abbreviating builtin names
* Stop abbreviating macro names half-randomly to 8 chars, this is no
longer 1990.
* Likewise for function names (in particular use doindex for a function
that is notably different from the classic index function).
* Rename a few things for more fidelity: eval is the builtin name, not
expr and your maketemp/mkstemp conform to mkstemp semantics for better
security.
* Rewrap a few comments that were ludicrously short.
No functional changes except improved accuracy of some error messages.

FreeBSD's struct in6_addr does not provide s6_addr32 directly. Add a small
