replace system's install command with a shell script
the historical (non-standardized) install command is really inappropriate for installing binaries/libraries on a system that utilizes memory-mapped executable files. rather than replacing an existing file atomically, it overwrites the existing file. this can cause running programs to see a partially-modified version of the file, resulting in unpredictable behavior, or SIGBUS. a MAP_COPY mode for mmap would get around this problem, but Linux lacks MAP_COPY. the shell script added with this commit works around the problem by writing temporary files and moving them into place. unlike the historical install utility, it also support a -l option for installing a symbolic link atomically, via the same method.
