Release libbsd 0.7.0

In case the support is not available, just stop building the
libbsd-ctor.a library, which is a nice to have thing, but should not
have been a hard requirement from the start. This should allow to
build libbsd on non-glibc based systems using another libc.

+.Ft FILE *
+.Fn fropen "void *cookie" "int (*readfn)(void *, char *, int)"
+.Ft FILE *
+.Fn fwopen "void *cookie" "int (*writefn)(void *, const char *, int)"
+.Sh DESCRIPTION
+The
+.Fn funopen
+function
+associates a stream with up to four
+.Dq Tn I/O No functions .
+Either
+.Fa readfn
+or
+.Fa writefn
+must be specified;
+the others can be given as an appropriately-typed
+.Dv NULL
+pointer.
+These
+.Tn I/O
+functions will be used to read, write, seek and
+close the new stream.
+.Pp
+In general, omitting a function means that any attempt to perform the
+associated operation on the resulting stream will fail.
+If the close function is omitted, closing the stream will flush
+any buffered output and then succeed.
+.Pp
+The calling conventions of
+.Fa readfn ,
+.Fa writefn ,
+.Fa seekfn
+and
+.Fa closefn
+must match those, respectively, of
+.Xr read 2 ,
+.Xr write 2 ,
+.Xr lseek 2 ,
+and
+.Xr close 2
+with the single exception that they are passed the
+.Fa cookie
+argument specified to
+.Fn funopen
+in place of the traditional file descriptor argument.
+.Pp
+Read and write
+.Tn I/O
+functions are allowed to change the underlying buffer
+on fully buffered or line buffered streams by calling
+.Xr setvbuf 3 .
+They are also not required to completely fill or empty the buffer.
+They are not, however, allowed to change streams from unbuffered to buffered
+or to change the state of the line buffering flag.
+They must also be prepared to have read or write calls occur on buffers other
+than the one most recently specified.
+.Pp
+All user
+.Tn I/O
+functions can report an error by returning \-1.
+Additionally, all of the functions should set the external variable
+.Va errno
+appropriately if an error occurs.
+.Pp
+An error on
+.Fn closefn
+does not keep the stream open.
+.Pp
+As a convenience, the include file
+.In stdio.h
+defines the macros
+.Fn fropen
+and
+.Fn fwopen
+as calls to
+.Fn funopen
+with only a read or write function specified.
+.Sh RETURN VALUES
+Upon successful completion,
+.Fn funopen
+returns a
+.Dv FILE
+pointer.
+Otherwise,
+.Dv NULL
+is returned and the global variable
+.Va errno
+is set to indicate the error.
+.Sh ERRORS
+.Bl -tag -width Er
+.It Bq Er EINVAL
+The
+.Fn funopen
+function
+was called without either a read or write function.
+The
+.Fn funopen
+function
+may also fail and set
+.Va errno
+for any of the errors
+specified for the routine
+.Xr malloc 3 .

+.Xr fclose 3 ,

+.Sh HISTORY
+The
+.Fn funopen
+functions first appeared in
+.Bx 4.4 .
+.Sh BUGS
+The
+.Fn funopen
+function
+may not be portable to systems other than
+.Bx .
+.Pp
+On
+.Fx ,
+.Ox
+and
+.Dx
+the
+.Fn funopen
+interface erroneously assumes that
+.Vt fpos_t
+is an integral type, and uses it in the
+.Fa seekfn
+hook; but because code using a
+.Fa seekfn
+hook will fail to build on systems where
+.Vt fpos_t
+is a struct, and it will need to be slightly fixed anyway, the
+implementation provided by libbsd (in the same way as
+.Nx )
+uses the correct
+.Vt off_t
+types.

+The

+function returns a preferred block size for reporting by system utilities

+.Xr ls 1
+and

+based on the value of the

+may be specified directly in bytes, or in multiples of a kilobyte by

+megabyte by specifying a number followed by ``M'' or ``m'' or in
+multiples of a gigabyte by specifying a number followed by ``G'' or
+``g''.
+Multiples must be integers.
+.Pp
+Valid values of
+.Ev BLOCKSIZE
+are 512 bytes to 1 gigabyte.
+Sizes less than 512 bytes are rounded up to 512 bytes, and sizes
+greater than 1 GB are rounded down to 1 GB.
+In each case
+.Fn getbsize
+produces a warning message.
+.Pp
+The
+.Fn getbsize
+function returns a pointer to a null-terminated string describing
+the block size, something like
+.Dq 1K-blocks .
+The memory referenced by
+.Fa headerlenp
+is filled in with the length of the string (not including the
+terminating null).
+The memory referenced by
+.Fa blocksizep
+is filled in with block size, in bytes.

+.Sh DESCRIPTION
+The
+.Nm
+functions manipulate stringlists, which are lists of
+strings that extend automatically if necessary.
+.Pp
+The
+.Ar StringList
+structure has the following definition:
+.Bd -literal -offset indent
+typedef struct _stringlist {
+	char	**sl_str;
+	size_t	  sl_max;
+	size_t	  sl_cur;
+} StringList;
+.Ed
+.Pp
+where:
+.Bl -tag -width "sl_str" -offset indent
+.It Ar sl_str
+is a pointer to the base of the array containing the list,
+.It Ar sl_max
+is the size of
+.Ar sl_str ,
+and
+.It Ar sl_cur
+is the offset in
+.Ar sl_str
+of the current element.
+.El
+.Pp
+The following stringlist manipulation functions are available:
+.Bl -tag -width "sl_delete()" -offset 2n
+.It Fn sl_init
+Create a stringlist.
+Returns a pointer to a
+.Ar StringList ,
+or
+.Dv NULL
+in case of failure.
+.It Fn sl_free
+Releases memory occupied by
+.Ar sl
+and the
+.Ar sl-\*[Gt]sl_str
+array.
+If
+.Ar freeall
+is non-zero, then each of the items within
+.Ar sl-\*[Gt]sl_str
+is released as well.
+.It Fn sl_add
+Add
+.Ar item
+to
+.Ar sl-\*[Gt]sl_str
+at
+.Ar sl-\*[Gt]sl_cur ,
+extending the size of
+.Ar sl-\*[Gt]sl_str .
+Returns zero upon success, \-1 upon failure.
+.It Fn sl_find
+Find
+.Ar item
+in
+.Ar sl ,
+returning
+.Dv NULL
+if it's not found.
+.It Fn sl_delete
+Remove
+.Ar item
+from the list.
+If
+.Ar freeit
+is non-zero, the string is freed.
+Returns
+.Dv 0
+if the name is found
+and
+.Dv \-1
+if the name is not found.
