Before, -[digest] would do the final calculation, however, this would
mean a property modifies state, which is bad. file: [de7aa6c8f4] check-in: [82801897d3] user: js, branch: trunk, size: 6483 [annotate] [blame] [check-ins using] [diff]

With this property, it's possible to specify whether the memory should
be protected from swapping or not. This makes it easier for e.g. the
crypto hash classes: They can now just always use OFSecureData without
wasting unswappable memory if it's not needed. file: [dbb6d31956] check-in: [e629dc83a9] user: js, branch: trunk, size: 6353 [annotate] [blame] [check-ins using] [diff]

Instead, explicitly declare them, as OF_ASSUME_NONNULL_{BEGIN,END} does
not apply to implicit return types. This means that after this commit,
all init methods have a nonnull return type, as they should have. file: [223f1ca854] check-in: [2f4e0df8be] user: js, branch: trunk, size: 5202 [annotate] [blame] [check-ins using] [diff]

This matches Apple's style. file: [280841ab34] check-in: [6b77a5dd8b] user: js, branch: trunk, size: 5184 [annotate] [blame] [check-ins using] [diff]

Casts are now written like types in variable declarations. file: [07e1179a49] check-in: [4af49a13c3] user: js, branch: trunk, size: 5123 [annotate] [blame] [check-ins using] [diff]

Forgot to add 2017, even though I already did quite some changes in
2017. file: [fb3b52794b] check-in: [44f45c2e35] user: js, branch: trunk, size: 5119 [annotate] [blame] [check-ins using] [diff]

While in practice they are usually the same, the C standard says that
only char does not have any alignment requirements. As (u)int*_t is
defined to be an integer type of the specified size, it does not mean
(u)int8_t needs to be char. file: [2324ca56a2] check-in: [19f7dc67af] user: js, branch: trunk, size: 4781 [annotate] [blame] [check-ins using] [diff]

OFHash is too generic, as this protocol is for cryptographic hashes. It
also solves the ambiguity of the +[hash] method (which is now
+[cryptoHash]), which conflicted with -[hash] on the class itself,
resulting in classes conforming to OFHash not being able to be used as a
key in an OFDictionary. file: [6b2637992f] check-in: [951f530aee] user: js, branch: trunk, size: 4775 [annotate] [blame] [check-ins using] [diff]

(U)INT_FAST*_MAX is broken on Android, which makes (u)int_fast*_t
dangerous to use while it does not provide any real speed benefit. file: [80ddf15097] check-in: [d3158d091f] user: js, branch: trunk, size: 4581 [annotate] [blame] [check-ins using] [diff]

This increases the required GCC version from 4.0 to 4.6 (exception:
Apple GCC, which already supports this with >= 4.0 starting with OS X
10.5). Since even GCC 4.6 is really old by now, there is no point in
still supporting something even older and making the code ugly because
of that. While some hardware and OS support was dropped from GCC 4.6
compared to GCC 4.0, there is nothing in there that would be an
interesting target with the exception of BeOS maybe - but a port to BeOS
can also be achieved using the Haiku support. The other dropped OSes are
mostly old versions of OSes while newer ones are still being supported
(and those newer versions of those OSes still support the same
hardware). file: [f2934a633d] check-in: [48980f2297] user: js, branch: trunk, size: 4592 [annotate] [blame] [check-ins using] [diff]

This is useful to calculate many hashes without allocating new objects. file: [1adbe2ccf4] check-in: [7c27db9fe0] user: js, branch: trunk, size: 4763 [annotate] [blame] [check-ins using] [diff]
