Cliff L. Biffle e787fa2d30 icetime: never silently truncate asc file lines 
icetime was reading the asc configuration file using a 128-byte line
buffer -- which is usually fine, but can cause it to truncate the names
of nets given in .sym lines if those names are very, very long.  The way
fgets was being used meant this went undetected.

Long net names like this can arise in deeply hierarchical designs,
particularly if there's a code generator involved.

This change:
1. Increases the buffer size to 64kiB.
2. Adds a truncation check that causes icetime to fail.

A more robust solution would manage the line buffer on the heap, since
the symbol gets copied into a std::string anyway, but this is a
workaround for now.

Salvador E. Tropea 1fb08362d9 Added a new config variable CHIPDB_SUBDIR. It determines the subdir name 
used in $(PREFIX)/share/ to install the chip database. This provides a
mechanism to choose a directory different than icebox (default).
I.e. fpga-icestorm/chipdb for Debian.

Sebastian Bøe f22f94619c icetime: fixed chipdb path issue for Arch Linux 
Icetime was hardcoding the path to chipdb as /usr/local/share causing
icetime to not find the chip db on Arch Linux where the prefix is just
/usr/share.

With this commit the PREFIX is passed as a preprocessor define and used
in icetime.cc to create the correct path. I don't know what the
canonical way of dealing with this is, but this was the least intrusive
way I could think of to get this fixed.
