If we are just copying data from one file to another, we don't need to
fill a complete buffer, just read a chunk at a time, and write it to the
output.
The -s flag previously called strip(1) on the installed file.
This patch changes install(1)'s behaviour to ignore -s.
Many makefiles use the -s flag, so it has to be recognised for
compatibility, however it does not have to do anything because
symbols do not negatively affect the functionallity of binaries.
Ignoring -s have the added benefit that the user do not need
to edit makefiles if they want the symbols that are useful for
debugging. If the user wants to strip away symbols, it can be
done manually or automatically by the package manager.

memmove moves a number of bytes, not pointers, so if you passed a number
of arguments that is larger than the pointer byte size, you could
end up crashing or skipping the install of a file and installing another
twice.
Also, argv was never decreased to match the moved arguments, so the -t
parameter was added in the NULL argv slot.
Also, since parsemode exits on failure, don't bother checking return
value in xinstall (this would never trigger anyway because mode_t can be
unsigned).
This is required in order for autoconf's AC_PROG_INSTALL to use the sbase
install. Otherwise it will fall back to the slow and sucky install-sh script
from automake.
Given the following commands:
touch 1.txt; install -D 1.txt d/2.txt
find d
The result without this fix:
d
d/2.txt
d/2.txt/1.txt
The result with this patch applied:
d
d/2.txt
