| * | major stdio overhaul, using readv/writev, plus other changes•••the biggest change in this commit is that stdio now uses readv to fill
the caller's buffer and the FILE buffer with a single syscall, and
likewise writev to flush the FILE buffer and write out the caller's
buffer in a single syscall.
making this change required fundamental architectural changes to
stdio, so i also made a number of other improvements in the process:
- the implementation no longer assumes that further io will fail
following errors, and no longer blocks io when the error flag is set
(though the latter could easily be changed back if desired)
- unbuffered mode is no longer implemented as a one-byte buffer. as a
consequence, scanf unreading has to use ungetc, to the unget buffer
has been enlarged to hold at least 2 wide characters.
- the FILE structure has been rearranged to maintain the locations of
the fields that might be used in glibc getc/putc type macros, while
shrinking the structure to save some space.
- error cases for fflush, fseek, etc. should be more correct.
- library-internal macros are used for getc_unlocked and putc_unlocked
now, eliminating some ugly code duplication. __uflow and __overflow
are no longer used anywhere but these macros. switch to read or
write mode is also separated so the code can be better shared, e.g.
with ungetc.
- lots of other small things.

| * | fix all implicit conversion between signed/unsigned pointers•••sadly the C language does not specify any such implicit conversion, so
this is not a matter of just fixing warnings (as gcc treats it) but
actual errors. i would like to revisit a number of these changes and
possibly revise the types used to reduce the number of casts required.

| * | simplify and optimize FILE lock handling | Rich Felker | 2011-03-24 | 4 | -11/+12 |
| * | fix non-atomicity of puts | Rich Felker | 2011-03-24 | 1 | -1/+5 |
| * | global cleanup to use the new syscall interface | Rich Felker | 2011-03-20 | 12 | -19/+19 |
| * | implement [v]swprintf | Rich Felker | 2011-03-18 | 2 | -0/+60 |
| * | implement wprintf family of functions•••this implementation is extremely ugly and inefficient, but it avoids a
good deal of code duplication and bloat. it may be cleaned up later to
eliminate the remaining code duplication and some of the warts, but i
don't really care about its performance.
note that swprintf is not yet implemented.

| * | optimize file locking: avoid cache-polluting writes to global storage | Rich Felker | 2011-03-16 | 2 | -3/+5 |
| * | partially-written draft of fmemopen, still in #if 0 | Rich Felker | 2011-03-14 | 1 | -3/+48 |
| * | implement flockfile api, rework stdio locking | Rich Felker | 2011-03-12 | 6 | -3/+54 |
| * | rewind must clear the error indicator in addition to seeking | Rich Felker | 2011-02-22 | 1 | -2/+5 |
| * | avoid referencing address of extern function from vdprintf•••this change is in preparation for upcoming PIC/shared library support.
the intent is to avoid going through the GOT, mainly so that dprintf
is operable immediately, prior to processing of relocations. having
dprintf accessible from the dynamic linker will make writing and
debugging the dynamic linker much easier.

| * | cleanup asprintf stuff | Rich Felker | 2011-02-20 | 2 | -2/+2 |
| * | fix %n specifier, again. this time it was storing the wrong value. | Rich Felker | 2011-02-20 | 1 | -7/+7 |
| * | fix printf %n specifier - missing breaks had it clobbering memory | Rich Felker | 2011-02-16 | 1 | -7/+7 |
| * | fix some pointer signedness issues (this was invalid C) | Rich Felker | 2011-02-14 | 2 | -3/+3 |
| * | cleaning up syscalls in preparation for x86_64 port•••- hide all the legacy xxxxxx32 name cruft in syscall.h so the actual
source files can be clean and uniform across all archs.
- cleanup llseek/lseek and mmap2/mmap handling for 32/64 bit systems
- alternate implementation for nice if the target lacks nice syscall
