qdist: return "(empty)" instead of NULL when printing an empty dist

Printf'ing a NULL string is undefined behaviour. Avoid it.

qdist: use g_renew and g_new instead of g_realloc and g_malloc.

This is safer against overflow. g_renew is available in all
version of glib, while g_realloc_n is only available in 2.24.

which we then leak when n == from->n. Fix it.

qdist: add module to represent frequency distributions of data

Sometimes it is useful to have a quick histogram to represent a certain
distribution -- for example, when investigating a performance regression
in a hash table due to inadequate hashing.

The appended allows us to easily represent a distribution using Unicode
characters. Further, the data structure keeping track of the distribution
is so simple that obtaining its values for off-line processing is trivial.

Example, taking the last 10 commits to QEMU:

Characters in commit title Count
-----------------------------------
39 1
48 1
53 1
54 2
57 1
61 1

qdist_inc(&dist, 39);

// -> [39.0,43.6)▂▂ █▂ ▂ ▄[75.4,80.0]
