[age restriction] progress 14/n - withdraw and deposit
Age restriction support for
- withdraw is done and tested
- deposit is done and tested
TODOs:
- melt/refresh/reveal
- link
------
Added functions
- TALER_age_restriction_commit
- TALER_age_commitment_derive
- TALER_age_commitment_hash
- TALER_age_restriction_commitment_free_inside
- Hash of age commitment passed around API boundaries
Exchangedb adjustments for denominations
- all prepared statements re: denominations now handle age_mask
- signature parameters adjusted
Hash and signature verification of /keys adjusted
- Hashes of (normal) denominations and age-restricted denominations are
calculated seperately
- The hash of the age-restricted ones will then be added to the other
hash
- The total hash is signed/verified
Tests for withdraw with age restriction added
- TALER_EXCHANGE_DenomPublickey now carries age_mask
- TALER_TESTING_cmd_withdraw_amount* takes age parameter
- TALER_TESTING_find_pk takes boolean age_restricted
- WithdrawState carries age_commitment and its hash
- withdraw_run derives new age commitment, if applicable
- Added age parameter to testing (13 as example)
Various Fixes and changes
- Fixes of post handler for /management/extensions
- Fixes for offline tool extensions signing
- Slight refactoring of extensions
- Age restriction extension simplified
- config is now global to extension
- added global TEH_age_restriction_enabled and TEH_age_mask in
taler-exchange-httpd
- helper functions and macros introduced
