SYMLINKS to install symlinked header files. INCSYMLINKS are installed with
'make includes'. This avoids using SYMLINKS and hacks with the 'linkinstall'
target in <bsd.links.mk>, as linksinstall occurs in 'make install' and hacks

Yet more improvements to bsd.README.
Ensure that the <readline/history.h> link to <readline/readline.h> is
installed too for 'make includes'. Also, avoid creating obj dir.
This is finally real fix for lib/12929.

readline.h of libedit had to move to subdirectory 'readline', due to the way
BSD makefiles work; this is better than potentially fragile Makefile hacks
