MFC r355718: Fix $() handling, broken since the beginning at r108014.

2019-12-27T18:52:43+00:00

Due to off-by-one error in brackets counting it consumed the rest of the
string, preventing later variables expansions.

We don't need shell protection for when we're expanding matches.

2018-09-22T15:32:53+00:00

Don't add it. This should fix when we do regepx matches against
variables we've set and fix wifi bring up.

Revert "devd: use C++ style casts"

It seems that nullptr is not yet supported by all compilers used by
FreeBSD. :(

devd: use static where possible

2018-07-29T08:43:05+00:00

We're not, yet, at C++11 capable on all our plaforms.

2018-06-28T01:45:53+00:00

Use a possibly slower, but C++98 compatibe way to iterate through the
string.

Noticed by: g++ 4.2.1 and Mark Millard

Safely quote all variable expansions.

2018-06-27T23:44:37+00:00

When expanding a variable set by a message from the kernel, safely
quote all arguments expanded when creating a command line for the
shell.

devd: correct two warnings

- catching a polymorphic type by value
- "output between 16 and 95 bytes into a destination of size 80"
