Release libbsd 0.5.0

The ChangeLog file is distributed, and cannot be regenerated outside
of the git repository, so do not remove it in DISTCLEANFILES, and move
the generation code into dist-hook, which also avoids unnecessary
computation during normal builds.

+.Nm fgetwln
+.Nd get a line of wide characters from a stream
+.Sh LIBRARY

+.Lb libbsd
+.Sh SYNOPSIS
+.In stdio.h
+.In bsd/wchar.h
+.Ft wchar_t *
+.Fn fgetwln "FILE * restrict stream" "size_t * restrict len"
+.Sh DESCRIPTION
+The
+.Fn fgetwln
+function
+returns a pointer to the next line from the stream referenced by
+.Fa stream .
+This line is
+.Em not
+a standard wide character string as it does not end with a terminating
+null wide character.
+The length of the line, including the final newline,
+is stored in the memory location to which
+.Fa len
+points.
+(Note, however, that if the line is the last
+in a file that does not end in a newline,
+the returned text will not contain a newline.)
+.Sh RETURN VALUES
+Upon successful completion a pointer is returned;
+this pointer becomes invalid after the next
+.Tn I/O
+operation on
+.Fa stream
+(whether successful or not)
+or as soon as the stream is closed.
+Otherwise,
+.Dv NULL
+is returned.
+The
+.Fn fgetwln
+function
+does not distinguish between end-of-file and error; the routines
+.Xr feof 3
+and
+.Xr ferror 3
+must be used
+to determine which occurred.
+If an error occurs, the global variable
+.Va errno
+is set to indicate the error.
+The end-of-file condition is remembered, even on a terminal, and all
+subsequent attempts to read will return
+.Dv NULL
+until the condition is
+cleared with
+.Xr clearerr 3 .
+.Pp
+The text to which the returned pointer points may be modified,
+provided that no changes are made beyond the returned size.
+These changes are lost as soon as the pointer becomes invalid.
+.Sh ERRORS
+.Bl -tag -width Er
+.It Bq Er EBADF
+The argument
+.Fa stream
+is not a stream open for reading.
+.El
+.Pp
+The
+.Fn fgetwln

+.Fc
+.Sh DESCRIPTION
+The
+.Fn fparseln
+function
+returns a pointer to the next logical line from the stream referenced by
+.Fa stream .
+This string is
+.Dv NUL
+terminated and it is dynamically allocated on each invocation.
+It is the responsibility of the caller to free the pointer.
+.Pp
+By default, if a character is escaped, both it and the preceding escape
+character will be present in the returned string.
+Various
+.Fa flags
+alter this behaviour.
+.Pp
+The meaning of the arguments is as follows:
+.Bl -tag -width "lineno"
+.It Fa stream
+The stream to read from.
+.It Fa len
+If not
+.Dv NULL ,
+the length of the string is stored in the memory location to which it
+points.
+.It Fa lineno
+If not
+.Dv NULL ,
+the value of the memory location to which is pointed to, is incremented
+by the number of lines actually read from the file.
+.It Fa delim
+Contains the escape, continuation, and comment characters.
+If a character is
+.Dv NUL
+then processing for that character is disabled.
+If
+.Dv NULL ,
+all characters default to values specified below.
+The contents of
+.Fa delim
+is as follows:
+.Bl -tag -width "delim[0]"
+.It Fa delim[0]
+The escape character, which defaults to
+.Cm \e ,
+is used to remove any special meaning from the next character.
+.It Fa delim[1]
+The continuation character, which defaults to
+.Cm \e ,
+is used to indicate that the next line should be concatenated with the
+current one if this character is the last character on the current line
+and is not escaped.
+.It Fa delim[2]
+The comment character, which defaults to
+.Cm # ,
+if not escaped indicates the beginning of a comment that extends until the
+end of the current line.
+.El
+.It Fa flags
+If non-zero, alter the operation of
+.Fn fparseln .
+The various flags, which may be
+.Em or Ns -ed
+together, are:
+.Bl -tag -width "FPARSELN_UNESCCOMM"
+.It Dv FPARSELN_UNESCCOMM
+Remove escape preceding an escaped comment.
+.It Dv FPARSELN_UNESCCONT
+Remove escape preceding an escaped continuation.
+.It Dv FPARSELN_UNESCESC
+Remove escape preceding an escaped escape.
+.It Dv FPARSELN_UNESCREST
+Remove escape preceding any other character.
+.It Dv FPARSELN_UNESCALL
+All of the above.
+.El
+.Pp
+.El
+.Sh RETURN VALUES
+Upon successful completion a pointer to the parsed line is returned;
+otherwise,
+.Dv NULL
+is returned.
+.Pp
+The
+.Fn fparseln
+function uses internally
+.Xr fgetln 3 ,
+so all error conditions that apply to
+.Xr fgetln 3 ,
+apply to
+.Fn fparseln .
+In addition
+.Fn fparseln
+may set

+and return
+.Dv NULL
+if it runs out of memory.
