[PATCH v4 0/5] histograms: Fix memory leak, logic bugs, legibility

[Stevie Alvarez <stevie.6strings@gmail.com>]

From: Stevie Alvarez (Google) <stevie.6strings@gmail.com>

Changes in v4:
 * Reorder enum traceeval_data_type numeric types for algorithmic access.
 * Reorder union traceeval_data numeric fields for legibility.
 * Remove parenthesis from function name in kerneldocs.
 * Optimize logic in type_alloc().
 * Distinguish internal vs public interfaces within include statements.
 * Rework copy_traceeval_data() logic for legibility.
 * Rework comparator return types to fix query and insert bugs.
 * update_entry() frees the entries old values to avoid a memory leak.

Steven, I didn't get around to adding in the cstring field to
traceeval_data, as I wasn't able to completely grasp what you were
looking for. My apologies.
