(1 << 31) is compiled as an int, and thus is equal to -2147483648. We
are trying to compare it against a long, which on 64-bit machines is
2147483648. This results in an infinite loop.

The touchid test was using a loop like:
for(i = 1; i < 0xffffffff; i <<= 1)
When 'i' is a 32-bit variable, this infinite loops as it goes from
0x80000000 to 0. 'i' is declared as 'long', which is 32-bit in 32-bit mode.

And put a comment in to explain why we're testing for a frac between .3 and
.6. We can't directly compare the frac since the floating/fixed point
conversion loses precision.

Previously, the input tests were working up to sizeof(mask) * 8, which
could be more than the arrays; the latter only being sized as
MAX_VALUATORS.
Hypothetically, if you were switching the stored valuator values to
double instead of uint32_t, and you attempted to set the 39th member of
a MAX_VALUATORS-sized (36) array, you'd probably end up smashing
ev->key_repeat into oblivion and then tripping the check for invalid
flags because you haven't yet put XIPointerEmulated into the valid flags
for XI_Motion. Probably.

The few features from the glib test suite we used can be replaced with
assert and printf. This patch is a simple replacement for these two
g_assert → assert
g_test_message → printf
g_test_init is removed and so is g_test_bug_base. g_test_run replaced with a
simple return 0.

The only remaining X-functions used in server are XNF*, the rest is converted to
plain alloc/calloc/realloc/free/strdup.
X* functions are still exported from server and x* macros are still defined in

sizeof(in.valuators.mask) * 8 == 40, but the valuators arrays only
holds 36 entries, so the test was smashing the stack when 36 < i < 40
(leading to core dumps on Solaris x86, since the return address was
overwritten with an invalid pointer).
