KO Myung-Hun bf88879b0d Revert "exec: prevent a command in a current dirctory from being executed"
This reverts commit 1b4d572b77.

An empty path is treated as a current directory in Unix, too.

KO Myung-Hun 1b4d572b77 exec: prevent a command in a current dirctory from being executed
A command in a current directory should be executed only if $PATH
contains the directory such as '.'.

This will improve the compatibility with Unix shell script and the
security.

KO Myung-Hun eb43e28996 Revert "exec: search commands in the current directory first on OS/2"
This reverts commit 89d461dd83.

To avoid the incompatibility with Unix shell scripts not expecting that
a current directory is searched first and the security problems, let a
user prepend "." to $PATH explicitly if needed.

KO Myung-Hun 89d461dd83 exec: search commands in the current directory first on OS/2
On OS/2, commands(executables) are searched in the current directory
before in $PATH.

KO Myung-Hun 20dbf6b45b Read in text mode in a needed place only
Converting CR+LF to LF in blocking_read() which is a underlying read
function, may affect to the functions which do not perform line-based
operation.

KO Myung-Hun 18ff277047 Write in binary mode through pipes
On kLIBC, a child inherits a translation mode of stdio/stdout/stderr
of a parent. So if setting stdio handles of a parent to text mode,
a child reads CR+LF as LF and write LF to CR+LF. Especially, LF to
CR+LF conversion causes many troubles in UNIX programs.

Instead, if a child inherts a child inherit a current translation mode,
where stdin is text mode, stdout and stderr are binary mode, a child
would write LF as is.

This is the way for OS/2 to survive in UNIX jungle.

For example, 'make check' of libiconv fails due to mismatch of CR+LF
and LF.

KO Myung-Hun cc49df380e fix mksh_sdirsep() and simplify mksh_vdirsep() on OS/2
mksh_sdirsep() returned a position of a more far directory separator
if '/' and '\' were mixed.

And mksh_sdirsep() returned a position of ':' even if a directory
separator follows. For example, in case of 'x:/', the position of
'/' should be returned not ':'.

mksh_vdirsep() were simplified with mksh_sdirsep().
