/*
This deals with only raw bits, which is bad form, but I prefer the design.
If the alpm_siglevel_t bitflag enum was not so strange, I wouldn't have
chosen to do this.

The bit flags are separated into two halves with a special case of the
"default value" where bit 32 (the MSB) is on. Reading from LSB to MSB,
the package flags consist of the first four bits. 6 unused bits follow.
The database flags consist of the next four bits. 17 unused bits follow.
Finally, the bit flag for ALPM_USE_DEFAULT is the MSB.

Here is the form of the package and database bitmask. Remember the
database flags are shifted to the left by 10 places.

BIT	DESCRIPTION
1	Signature checking is enabled for packages or databases respectively.
2	Signature checking is optional, used only when available.
3	MARGINAL_OK?
4	UNKNOWN_OK?

A setting of TrustAll in pacman.conf enables MARGINAL_OK and UNKNOWN_OK.
These two flags are not enabled separately from one another.

ALPM_SIG_USE_DEFAULT is the default value when set_default_siglevel is never
called but I have no idea what that could mean when this is the value of the default.
This seems to be a circular argument with no end.
