Git's source code assumes that unsigned long is at least as precise as time_t. Which is incorrect, and causes a lot of problems, in particular where unsigned long is only 32-bit (notably on Windows, even in 64-bit versions). So let's just use a more appropriate data type instead. In preparation for this, we introduce the new `timestamp_t` data type. By necessity, this is a very, very large patch, as it has to replace all timestamps' data type in one go. As we will use a data type that is not necessarily identical to `time_t`, we need to be very careful to use `time_t` whenever we interact with the system functions, and `timestamp_t` everywhere else.
