b10d86bcaa Introduce get_cds1 to merge common code that checks for 0=default_drive,1=A,etc. 
Make load_transfer() static.

896908d6f7 Eliminate DosGetFile -- it is no longer necessary because the filename 
is already copied from the fnode.

9a415b14b2 Fix a regression with sft_flags overwriting what dos_open wrote so file 
dates/times would always be updated, even for reads!

a0382d32e4 Eliminate dos_setfsize, dos_setftime, and dos_lseek, by just using the SFT. 
dos_setfsize still needed to merge changes for SHARE so the call was replaced
by a new dos_merge_file_changes() call.


git-svn-id: https://svn.code.sf.net/p/freedos/svn/kernel/trunk@1405 6ac86273-5f31-0410-b378-82cca8765d1b

4a81e6e9a2 Let merge_file_changes operate directly on the other SFTs. 
dos_setfattr with SHARE now closes open SFTs referring to that file
in compat mode.

f9f2fe447d Eliminate dos_getftime, dos_getfsize, and dos_getfattr_fd, because we can 
now get these properties directly from the SFT.

d7d201a53b This is the main change to eliminate far fnodes. 
SFT info is copied from and to the two near fnodes.
Some cleanups still follow.

0ad01cd768 Handle sft_count before calling dos_open and after calling dos_close so 
the SFT is open for longer, during fatfs.c operations.

affddaaf64 Handle dos_getfattr and dos_setfattr directly at the directory level, instead 
of opening the file, to avoid needing to claim SFTs in later changes.
Clarify and implement parts of the correct SHARE behaviour.

ae3d48ab33 Change how DosGetExtFree checks for drive so int 21h/7303h more lax about path given, support driver specifier with or without slash (C: or C:\) and just slash (\) for current drive (does allow some additional bogus paths to return success)

b0e54ff704 (with a little help from Arkady) 
inthndler.c, chario.c, break.c simplifications and cleanups.
Pass a near pointer to the far pointer that points to the device instead
of an SFT index (in general).
Make cooked_write much faster by only testing for input every 32
characters.
No longer test for ctl_s on syscon if writing to the printer: just
read from the printer which will return zero characters.
Fix reading/writing zero characters by returning "256" (special code).
Adjust interfaces in other files.
