Even though mlock(2) was standardized in POSIX.1-2001, vendors did
implement it prior that point.

fabs(3m) is customarily inlined, but it's not, one has to link with -lm.
Since fabs(3m) is the only reference, it makes more sense to avoid it.

With this, we introduce the make variable 'libdir', which differs from
'LIBDIR' not only in casing, but also by being the absolute path to
the library installation directory.  This variable is intentionally
compatible with the GNU coding standards.

When --libdir is given an absolute path, it is considered as a value
according to GNU coding standards, and the variables LIBDIR and libdir
will be this:

    LIBDIR=
    libdir=/absolute/path

When --libdir is given a relative path (just the name of the desired
library directory), or not given at all, it is considered as a
"traditional" OpenSSL value, and the variables LIBDIR and libdir will
be this:

    LIBDIR=relativepath
    libdir=$(INSTALLTOP)/$(LIBDIR)

makedepend makes lesser sense in a throw-away build like CI, but
it spares some computational time, because with MSVC it takes
separate per-file compiler invocation.

As it turns out gcc -pedantic doesn't seem to consider __uint128_t

SPARC condition in __SIZEOF_INT128__==16 is rather performance thing
than portability. Even though compiler advertises int128 capability,
corresponding operations are inefficient, because they are not
directly backed by instruction set.

When compiling with -Wall on a machine with an old compiler it gives a false
positive that the dc variable which is a structure of type DISPLAY_COLUMNS
could be used uninitialised. In fact the dc variable's members will always get
set in the case it is used, otherwise it is left uninitialised.
This fix just causes the dc variable's members to always get initialised to 0
at declaration, so the false positive will not get flagged.
