Alexander Ziaee ff2bc64159 manuals: Fix Fx and nearby mechanical typos
Fix compiler warnings related to the Fx macro, as well as all other
mechanical typos that were visible within one screenful of them. These
cause rendering glitches on various toolchains with various of the five
and a half decades of rich output formats and tooling manpages scale to.

The *x macro set specifies operating systems. These macros take the rest
of the line as an argument. Sometimes, a space was not used to separate
the argument of Fx and the trailing period. Another, FreeBSD Foundation
was misrepresented as an operating system version instead of an author.
Two more had other parts of the sentence supplied as an argument to Fx.

While I had those open, fix the other mechancial typos visible on those
specific screenfulls. Fix a list width glitch, correct section typo
AUTHOR to AUTHORS, and switch AUTHORS sections containing prose to
prose-mode so that they wrap freely when rendered.

.Sh NAME
.Nm stdc_bit_ceil
.Nd round up to the next power of\~2
.Sh SYNOPSIS
.Lb libc
.In stdbit.h
.Ft unsigned char
.Fn stdc_bit_ceil_uc "unsigned char value"
.Ft unsigned short
.Fn stdc_bit_ceil_us "unsigned short value"
.Ft unsigned int
.Fn stdc_bit_ceil_ui "unsigned int value"
.Ft unsigned long
.Fn stdc_bit_ceil_ul "unsigned long value"
.Ft unsigned long long
.Fn stdc_bit_ceil_ull "unsigned long long value"
.Ft typeof Ns Pq Em value
.Fn stdc_bit_ceil "value"
.Sh DESCRIPTION
The
.Nm stdc_bit_ceil_ Ns Em type Ns ()
family of functions rounds
.Fa value
up to the next power of\~2, where
.Fa value
is of type
.Va unsigned char ,
.Va unsigned short ,
.Va unsigned int ,
.Va unsigned long ,
or
.Va unsigned long long
for
.Em type
being
.Sy uc ,
.Sy us ,
.Sy ui ,
.Sy ul ,
or
.Sy ull
respectively.
The
.Fn stdc_bit_ceil "value"
type-generic macro picks the appropriate
.Nm stdc_bit_ceil_ Ns Em type Ns ()
function based on the type of
.Fa value .
.Sh RETURN VALUES
Returns
.Fa value
round up to the next power of\~2.
If this value is not representable,
0\~is returned.
.Sh SEE ALSO
.Xr stdbit 3 ,
.Xr stdc_bit_floor 3
.Sh STANDARDS
The
.Nm stdc_bit_ceil_ Ns Em type Ns ()
family of functions and the
.Fn stdc_bit_ceil
type-generic macro conform to
.St -isoC-2023 .
.Sh HISTORY
The
.Nm stdc_bit_ceil_ Ns Em type Ns ()
family of functions and the
.Fn stdc_bit_ceil
type-generic macro were added in
.Fx 15.1 .
