Fighting the good fight.

Move libfmt, libutf into subdirectories of lib9.

Add poll-based socket i/o to libthread, so that we can
avoid using multiple procs when possible, thus removing
dependence on crappy pthreads implementations.

Convert samterm, acme to the single-proc libthread.

Bring libcomplete, acme up-to-date w.r.t. Plan 9 distribution.

-.SH DESCRIPTION
-.I Print
-writes text to the standard output.
-.I Fprint
-writes to the named output
-file descriptor.
-.I Sprint
-places text
-followed by the NUL character
-.RB ( \e0 )
-in consecutive bytes starting at
-.IR s ;
-it is the user's responsibility to ensure that
-enough storage is available.
-Each function returns the number of bytes
-transmitted (not including the NUL
-in the case of
-.IR sprint ),
-or
-a negative value if an output error was encountered.
-.PP
-.I Snprint
-is like
-.IR sprint ,
-but will not place more than
-.I len
-bytes in
-.IR s .
-Its result is always NUL-terminated and holds the maximal
-number of characters that can fit.
-.I Seprint
-is like
-.IR snprint ,
-except that the end is indicated by a pointer
-.I e
-rather than a count and the return value points to the terminating NUL of the
-resulting string.
-.I Smprint
-is like
-.IR sprint ,
-except that it prints into and returns a string of the required length, which is
-allocated by
-.IR malloc (3).
-.PP
-The routines
-.IR runesprint ,
-.IR runesnprint ,
-.IR runeseprint ,
-and
-.I runesmprint
-are the same as
-.IR sprint ,
-.IR snprint ,
-.IR seprint
-and
-.I smprint
-except that their output is rune strings instead of byte strings.
-.PP
-Finally, the routines
-.IR vfprint ,
-.IR vsnprint ,
-.IR vseprint ,
-.IR vsmprint ,
-.IR runevsnprint ,
-.IR runevseprint ,
-and
-.I runevsmprint
-are like their
-.BR v-less
-relatives except they take as arguments a
-.B va_list
-parameter, so they can be called within a variadic function.
-The Example section shows a representative usage.
-.PP
-Each of these functions
-converts, formats, and prints its
-trailing arguments
-under control of a
-.IR format 
-string.
-The
-format
-contains two types of objects:
-plain characters, which are simply copied to the
-output stream,
-and conversion specifications,
-each of which results in fetching of
-zero or more
-arguments.
-The results are undefined if there are arguments of the
-wrong type or too few
-arguments for the format.
-If the format is exhausted while
-arguments remain, the excess
-is ignored.
-.PP
-Each conversion specification has the following format:
-.IP
-.B "% [flags] verb
-.PP
-The verb is a single character and each flag is a single character or a
-(decimal) numeric string.
-Up to two numeric strings may be used;
-the first is called
-.IR width ,
-the second
-.IR precision .
-A period can be used to separate them, and if the period is
-present then
-.I width
-and
-.I precision
-are taken to be zero if missing, otherwise they are `omitted'.
-Either or both of the numbers may be replaced with the character
-.BR * ,
-meaning that the actual number will be obtained from the argument list
-as an integer.
-The flags and numbers are arguments to
-the
-.I verb
-described below.
-.PP
-The numeric verbs
-.BR d ,
-.BR i ,
-.BR u ,
-.BR o ,
-.BR b ,
-.BR x ,
-and
-.B X
-format their arguments in decimal, decimal,
-unsigned decimal, octal, binary, hexadecimal, and upper case hexadecimal.
-Each interprets the flags
-.BR 0 ,
-.BR h ,
-.BR hh ,
-.BR l ,
-.BR + ,
-.BR - ,
-.BR , ,
-and
-.B #
-to mean pad with zeros,
-short, byte, long, always print a sign, left justified, commas every three digits,
-and alternate format.
-Also, a space character in the flag
-position is like
-.BR + ,
-but prints a space instead of a plus sign for non-negative values.
-If neither
-short nor long is specified,
-then the argument is an
-.BR int .
-If an unsigned verb is specified,
-then the argument is interpreted as a
-positive number and no sign is output;
-space and
-.B +
-flags are ignored for unsigned verbs.
-If two
-.B l
-flags are given,
-then the argument is interpreted as a
-.B vlong
-(usually an 8-byte, sometimes a 4-byte integer).
-If
-.I precision
-is not omitted, the number is padded on the left with zeros
-until at least
-.I precision
-digits appear.
-If
-.I precision
-is explicitly 0, and the number is 0,
-no digits are generated, and alternate formatting
-does not apply.
-Then, if alternate format is specified,
-for
-.B o
-conversion, the number is preceded by a
-.B 0
-if it doesn't already begin with one.
-For non-zero numbers and
-.B x
-conversion, the number is preceded by
-.BR 0x ;
-for
-.B X
-conversion, the number is preceded by
-.BR 0X .
-Finally, if
-.I width
-is not omitted, the number is padded on the left (or right, if
-left justification is specified) with enough blanks to
-make the field at least
-.I width
-characters long.
-.PP
-The floating point verbs
-.BR f ,
-.BR e ,
-.BR E ,
-.BR g ,
-and
-.B G
-take a
-.B double
-argument.
-Each interprets the flags
-.BR 0 ,
-.BR L
-.BR + ,
-.BR - ,
-and
-.B #
-to mean pad with zeros,
-long double argument,
-always print a sign,
-left justified,
-and
-alternate format.
-.I Width
-is the minimum field width and,
-if the converted value takes up less than
-.I width
-characters, it is padded on the left (or right, if `left justified')
-with spaces.
-.I Precision
-is the number of digits that are converted after the decimal place for
-.BR e ,
-.BR E ,
-and
-.B f
-conversions,
-and
-.I precision
-is the maximum number of significant digits for
-.B g
-and
-.B G
-conversions.
-The 
-.B f
-verb produces output of the form
-.RB [ - ] digits [ .digits\fR].
-.B E
-conversion appends an exponent
-.BR E [ - ] digits ,
-and
-.B e
-conversion appends an exponent
-.BR e [ - ] digits .
-The
-.B g
-verb will output the argument in either
-.B e
-or
-.B f
-with the goal of producing the smallest output.
-Also, trailing zeros are omitted from the fraction part of
-the output, and a trailing decimal point appears only if it is followed
-by a digit.
-The
-.B G
-verb is similar, but uses
-.B E
-format instead of
-.BR e .
-When alternate format is specified, the result will always contain a decimal point,
-and for
-.B g
-and
-.B G
-conversions, trailing zeros are not removed.
-.PP
-The
-.B s
-verb copies a string
-(pointer to
-.BR char )
-to the output.
-The number of characters copied
-.RI ( n )
-is the minimum
-of the size of the string and
-.IR precision .
-These
-.I n
-characters are justified within a field of
-.I width
-characters as described above.
-If a
-.I precision
-is given, it is safe for the string not to be nul-terminated
-as long as it is at least
-.I precision
-characters (not bytes!) long.
-The
-.B S
-verb is similar, but it interprets its pointer as an array
-of runes (see
-.IR utf (7));
-the runes are converted to
-.SM UTF
-before output.
-.PP
-The
-.B c
-verb copies a single
-.B char
-(promoted to
-.BR int )
-justified within a field of
-.I width
-characters as described above.
-The
-.B C
-verb is similar, but works on runes.
-.PP
-The
-.B p
-verb formats a pointer value.
-At the moment, it is a synonym for
-.BR x ,
-but that will change if pointers and integers are different sizes.
-.PP
-The
-.B r
-verb takes no arguments; it copies the error string returned by a call to
-.IR strerror (3)
-with an argument of
-.IR errno.
-.PP
-Custom verbs may be installed using
-.IR fmtinstall (3).
-.SH EXAMPLE
-This function prints an error message with a variable
-number of arguments and then quits.
-.IP
-.EX
-.ta 6n +6n +6n
-void fatal(char *msg, ...)
-{
-	char buf[1024], *out;
-	va_list arg;
-
-	out = vseprint(buf, buf+sizeof buf, "Fatal error: ");
-	va_start(arg, msg);
-	out = vseprint(out, buf+sizeof buf, msg, arg);
-	va_end(arg);
-	write(2, buf, out-buf);
-	exit(1);
-}
-.EE
-.SH SEE ALSO
-.IR fmtinstall (3),
-.IR fprintf (3),
-.IR utf (7)
-.SH DIAGNOSTICS
-Routines that write to a file descriptor or call
-.IR malloc
-set
-.IR errstr .
-.SH BUGS
-The formatting is close to that specified for ANSI
-.IR fprintf (3);
-the main difference is that
-.B b
-and
-.B r
-are not in ANSI and some
-.B C9X
-verbs are missing.
-Also, and distinctly not a bug,
-.I print
-and friends generate
-.SM UTF
-rather than
-.SM ASCII.
-.PP
-There is no
-.BR runeprint ,
-.BR runefprint ,
-etc. because runes are byte-order dependent and should not be written directly to a file; use the
-UTF output of
-.I print
-or
-.I fprint
-instead.
-Also,
-.I sprint
-is deprecated for safety reasons; use
-.IR snprint ,
-.IR seprint ,
-or
-.I smprint
-instead.
-Safety also precludes the existence of
-.IR runesprint .
