4e6b157062 Locale *is* used in strto*l*(), at least for isspace(), so remove
'locale not used' statement from comments and BUGS section of manpage.

strtol(): fix non-portable 'cutoff' calculation using the same method as
in strtoll().

Cleanup 'cutoff' calculation, remove unneded casts. Misc. cleanup to
make all functions looks the same.

Implement EINVAL reaction per POSIX, document it in manpage, corresponding
POSIX example quotes here:

------------------------------------------------
If the subject sequence is empty or does not have the expected form, no
conversion is performed; the value of str is stored in the object pointed
to by endptr, provided that endptr is not a null pointer.

If no conversion could be performed, 0 shall be returned and errno may be
set to [EINVAL].

[EINVAL] The value of base is not supported.

Since 0, {LONG_MIN} or {LLONG_MIN}, and {LONG_MAX} or {LLONG_MAX} are
returned on error and are also valid returns on success, an application
wishing to check for error situations should set errno to 0, then call
strtol( ) or strtoll ( ), then check errno.

033d275cb0 PT_STEP in ptrace(2) man page is described as 'addr and data fields
are not used'.  This is incorrect, as addr must be passed (caddr_t)1
to do anything useful.  The source for gdb and a short test program
will confirm that this man page was in error.

aeb7f4bac4 Internal seeks are overoptimized. They should remember fp->_offset only for
plain regular files, i.e. files with __SOPT flag set. Fix it, so ftell(stdout)

924888f977 Move all stdio internal flags processing and setting out of __sread(),
__swrite() and __sseek() to higher level. According to funopen(3) they all
are just wrappers to something like standard read(2), write(2) and
lseek(2), i.e. must not touch stdio internals because they are replaceable
with any other functions knows nothing about stdio internals. See example
of funopen(3) usage in sendmail sources f.e.

NOTE: this is original stdio bug, not result of my range checkin added.

e54bc118c1 Add more EOVERFLOW checks.
When file offset tends to be negative due to internal and ungetc buffers
additions counted, try to discard some ungetc data first, then return EBADF.
Later one can happens if lseek(fileno(fd),...) called f.e. POSIX says that
ungetc beyond beginning of the file results are undefined, so we can just
discard some of ungetc data in that case.

Don't rely on gcc cast when checking for overflow, use OFF_MAX.

Cosmetique.

719077d1be Fix a bug in lseek which caused the loader to fail on some gzipped
kernels.  The error message was "elf_loadexec: cannot seek".

Libstand maintains a read-ahead buffer for each open file, so that
it can read in chunks of 512 bytes for greater efficiency.  When
the loader tries to lseek forward in a file by a small amount, it
sometimes happens that the target file offset is already in the
read-ahead buffer.  But the lseek code simply discarded the contents
of that buffer and performed a seek directly on the underlying
file.  This resulted in an attempt to seek backwards in the file,
since some of the data has already been read into the read-ahead
buffer.  Gzipped data streams cannot seek backwards, so an error
was returned.

This commit adds code which checks to see if the desired file offset
is already in the read-ahead buffer.  If it is, the code simply
adjusts the buffer pointer and length, thereby avoiding a reverse
seek on the gzipped data stream.

I incorporated a suggestion from Matt Dillon which saved a little
bit of code in this fix.
