it actually doesn't assert the value
becase we now use same if statement
for the assertion but hope it to be
even a little better than no covarage.

...if users *really* want to. They opt-in at run time by setting

    LIBERASURECODE_WRITE_LEGACY_CRC=1

in the environment; leaving it unset, set to an empty string, or set to
the string "0" continues to write zlib crcs.

UpgradeImpact
=============
This option is intended to allow a smooth upgrade from liberasurecode
1.5.0 and earlier in a system with multiple readers and writers:

  * Before upgrade, ensure the environment variable is set on all nodes.
    This will be ignored by earlier versions.
  * Upgrade liberasurecode on each node in the system, restarting any
    services that use it. Every node continues writing CRCs that are
    still usable by nodes that have not yet upgraded.
  * Now that every node is capable of reading zlib CRCs, remove the
    environment variable from each node to start writing new CRCs.

If you are already using 1.6.0 or later, just upgrade normally.

Apparently upstream now requires that you log in?

*Hopefully*, this will make it "standard" enough that GitHub will
call it out as the BSD-2-Clause that it is.

Compilers are getting smarter, and we started getting this:

libec_slap.c: In function 'test_hd_code':
libec_slap.c:285:14: error: 'frags.array' may be used uninitialized
 in this function [-Werror=maybe-uninitialized]

The fix is to consume the error code in such a way that the
test proceeds further only when frags are indeed initialized.

These aren't C strings; we shouldn't be using strncpy and friends.
