Some MacOS systems might not have GNU Bison installed, or have openssl installed. In such instances the host versions of those can be used, with a few tweaks around the edges to make them work. This commit addresses these by: * Relaxing a HAVE_CRYPTO check for __APPLE__, since the inclusion of the machine-specific headers isn't dependent on openssl being installed; * If the non-GNU version of bison on MacOS is being used, define any missing YY* variables, and add a compiler #warning so we log something. This also updates the CI scripts to default to the system versions of bison and removes openssl as a core dependency -- it's more likely openssl is going to be installed, so removing it here will mean we can catch the case for just the MacOS-specific failures, and the inclusion of openssl on other OSes should cover the rest.

Explicitly cast "char" to "unsigned char" when assigned to "int" to prevent sign extension from breaking comparions against EOF or passing invalid arguments to ctype functions.

Original commit message by deraadt: (unsigned) means (unsigned int) which on ptrdiff_t or size_t or other larger types really is a range reduction... Almost any cast to (unsigned) is a bug.

This commit modifies the GoT main branch to be able to compile it under linux.

Feature requested by naddy. ok naddy, who also suggested some tweaks that will arrive shortly

yacc has been complaining about "shift/reduce conflicts" since commit 16c4be8c1cab9456f9dd0468c27f8ab73235737e Revert that change for now. Not sure how it can be done properly. In any case, allowing empty config blocks is not very important.

This is the beginning of support for naddy's suggestion to break this out similar to git. More code to come from stsp. ok stsp@

Make use of this in 'got clone' to persist -R option arguments given on the command line in the cloned repository's got.conf(5) file.

Set fetch-all-branches in the got.conf(5) file created by 'got clone -a' in order to make a future 'got fetch' act like 'got fetch -a' by default.

Cast printf arguments of type time_t and off_t to long long to match the %lld format specifier on platforms where this might not be the case. In parse.y, switch the number variable to long long because all its interactions are with that type anyway. ok millert stsp
