2019-03-04	On device restart, if a hashsig key was generated using the pseudorandom	Paul Selkirk
	method, and it's missing one or more lmots keys, those keys can be regenerated. OTOH, if an lms key is damaged or missing, it's still a fatal error, because that's the only place we record the current q value.
2019-03-04	Use the hashsig pseudorandom key generation method if the key is exportable.	Paul Selkirk

2018-11-14	Add some yields to hal_hashsig_ks_init, so other tasks can run while we're ↵	Paul Selkirk
	rebuilding the hash tree.
2018-08-12	Clean up builds for *BSD/clang.	Paul Selkirk
	Move lm[ot]s_algorithm_t definitions to hal.h, prefix all public symbols with 'hal_'. Remove some unused functions. Wrap hal_pkey_slot_t initializers in an extra set of curly braces. Remove an unused-argument kludge (x=x;) because gcc doesn't care, and clang complains. Make timersub a proper macro. Add some casts to printf arguments, because !@#$ printf formats.
2018-07-24	Change the rest of the hashsig ASN.1 wrapper functions to static inline, for ↵	Paul Selkirk
	consistency.
2018-07-24	A recent(?) version of arm-none-eabi-gcc decided to make storage for enums	Paul Selkirk
	the minimum size necessary, so hal_asn1_decode_lms_algorithm and hal_asn1_decode_lmots_algorithm were writing 4 bytes of data into 1-byte variables. Hilarity ensued. Yes, I already knew that conflating enum with uint32_t was a bad idea, I was just being lazy. For that matter, sizeof(size_t) isn't guaranteed either, although arm-none-eabi-gcc treats it as 32 bits on this 32-bit target (for now), so exercise proper data hygiene in hal_asn1_decode_size_t as well.
2018-07-24	Add protection against trying to use hashsig while the restart mechanism is ↵	Paul Selkirk
	rebuilding the tree.
2018-05-01	Add some yields to try to improve responsiveness during hashsig key ↵	Paul Selkirk
	generation and deletion.
2018-04-19	Reconstruct the hashsig hash tree(s) on device restart.	Paul Selkirk

2018-04-19	Update to draft-10: clarifications and Test Case 2;	Paul Selkirk
	add ability to export public key to xdr for interop testing
2018-04-19	For 2^w and 2^h, replace hard-coded w2 and h2 values with 1<<w and 1<<h.	Paul Selkirk

2018-04-19	Fold the coef* functions into a single function, because that really was ↵	Paul Selkirk
	premature optimization.
2018-04-19	Fix coef4, which was swapping digits	Paul Selkirk

2018-04-19	Implement hash-based signatures, per draft-mcgrew-hash-sigs-08.txt	Paul Selkirk
