Merge pull request #9623 from yoav-steinberg/upgrade_jemalloc_5.2.1
Upgraded to jemalloc 5.2.1 from 5.1.0.
Cherry picked all relevant fixes (by diffing our 5.1.0 to upstream 5.10 and finding relevant commits).
Details of what was done:
[cherry-picked] fd7d51c 2021-05-03 Resolve nonsense static analysis warnings (Oran Agra)
[cherry-picked] 448c435 2020-09-29 Fix compilation warnings in Lua and jemalloc dependencies (#7785) (YoongHM)
[skipped - already in upstream] 9216b96 2020-09-21 Fix compilation warning in jemalloc's malloc_vsnprintf (#7789) (YoongHM)
[cherry-picked] 88d71f4 2020-05-20 fix a rare active defrag edge case bug leading to stagnation (Oran Agra)
[skipped - already in upstream] 2fec7d9 2019-05-30 Jemalloc: Avoid blocking on background thread lock for stats.
[cherry-picked] 920158e 2018-07-11 Active defrag fixes for 32bit builds (again) (Oran Agra)
[cherry-picked] e8099ca 2018-06-26 add defrag hint support into jemalloc 5 (Oran Agra)
[re-done] 4e729fc 2018-05-24 Generate configure for Jemalloc. (antirez)
Additionally had to do this:
7727cc2 2021-10-10 Fix defrag to support sharded bins in arena (added in v5.2.1) (Yoav Steinberg)
When reviewing please look at all except the first commit which is just replacing 5.1.0 with 5.2.1 sources.
Also I think we should merge this without squashing to preserve the changes we did to to jemalloc.

We can then split all the + * remaining size classes into groups. The size classes in a group are spaced + * such that they cover allocation request sizes in a power-of-2 range.

We'll often talk in terms of + * lg_base and lg_delta. For each of these groups then, we have that + * lg_delta == lg_base - SC_LG_NGROUP. + * The size classes in a group with a given lg_base and lg_delta (which, recall, + * can be computed from lg_base for these groups) are therefore: + * base + 1 * delta + * which covers allocations in (base, base + 1 * delta] + * base + 2 * delta + * which covers allocations in (base + 1 * delta, base + 2 * delta]. + * base + 3 * delta + * which covers allocations in (base + 2 * delta, base + 3 * delta]. + * ... + * base + SC_NGROUP * delta ( == 2 * base) + * which covers allocations in (base + (SC_NGROUP - 1) * delta, 2 * base]. + * (Note that currently SC_NGROUP is always 4, so the "..." is empty in + * practice.) + * Note that the last size class in the group is the next power of two (after + * base), so that we've set up the induction correctly for the next group's + * selection of delta. + * + * Now, let's start considering the first few size classes. Two extra constants + * come into play here: LG_QUANTUM and SC_LG_TINY_MIN. LG_QUANTUM ensures + * correct platform alignment; all objects of size (1 << LG_QUANTUM) or larger + * are at least (1 << LG_QUANTUM) aligned; this can be used to ensure that we + * never return improperly aligned memory, by making (1 << LG_QUANTUM) equal the + * highest required alignment of a platform. For allocation sizes smaller than + * (1 << LG_QUANTUM) though, we can be more relaxed (since we don't support + * platforms with types with alignment larger than their size). To allow such + * allocations (without wasting space unnecessarily), we introduce tiny size + * classes; one per power of two, up until we hit the quantum size. There are + * therefore LG_QUANTUM - SC_LG_TINY_MIN such size classes. + * + * Next, we have a size class of size (1 << LG_QUANTUM). This can't be the + * start of a group in the sense we described above (covering a power of two + * range) since, if we divided into it to pick a value of delta, we'd get a + * delta smaller than (1 << LG_QUANTUM) for sizes >= (1 << LG_QUANTUM), which + * is against the rules. + * + * The first base we can divide by SC_NGROUP while still being at least + * (1 << LG_QUANTUM) is SC_NGROUP * (1 << LG_QUANTUM). We can get there by + * having SC_NGROUP size classes, spaced (1 << LG_QUANTUM) apart. These size + * classes are: + * 1 * (1 << LG_QUANTUM) + * 2 * (1 << LG_QUANTUM) + * 3 * (1 << LG_QUANTUM) + * ... (although, as above, this "..." is empty in practice) + * SC_NGROUP * (1 << LG_QUANTUM). + * + * There are SC_NGROUP of these size classes, so we can regard it as a sort of + * pseudo-group, even though it spans multiple powers of 2, is divided + * differently, and both starts and ends on a power of 2 (as opposed to just + * ending). SC_NGROUP is itself a power of two, so the first group after the + * pseudo-group has the power-of-two base SC_NGROUP * (1 << LG_QUANTUM), for a + * lg_base of LG_QUANTUM + SC_LG_NGROUP. We can divide this base into SC_NGROUP + * sizes without violating our LG_QUANTUM requirements, so we can safely set + * lg_delta = lg_base - SC_LG_GROUP (== LG_QUANTUM). + * + * So, in order, the size classes are: + * + * Tiny size classes: + * - Count: LG_QUANTUM - SC_LG_TINY_MIN. + * - Sizes: + * 1 << SC_LG_TINY_MIN + * 1 << (SC_LG_TINY_MIN + 1) + * 1 << (SC_LG_TINY_MIN + 2) + * ... + * 1 << (LG_QUANTUM - 1) + * + * Initial pseudo-group: + * - Count: SC_NGROUP + * - Sizes: + * 1 * (1 << LG_QUANTUM) + * 2 * (1 << LG_QUANTUM) + * 3 * (1 << LG_QUANTUM) + * ... + * SC_NGROUP * (1 << LG_QUANTUM) + * + * Regular group 0: + * - Count: SC_NGROUP + * - Sizes: + * (relative to lg_base of LG_QUANTUM + SC_LG_NGROUP and lg_delta of + * lg_base - SC_LG_NGROUP) + * (1 << lg_base) + 1 * (1 << lg_delta) + * (1 << lg_base) + 2 * (1 << lg_delta) + * (1 << lg_base) + 3 * (1 << lg_delta) + * ... + * (1 << lg_base) + SC_NGROUP * (1 << lg_delta) [ == (1 << (lg_base + 1)) ] + * + * Regular group 1: + * - Count: SC_NGROUP + * - Sizes: + * (relative to lg_base of LG_QUANTUM + SC_LG_NGROUP + 1 and lg_delta of + * lg_base - SC_LG_NGROUP) + * (1 << lg_base) + 1 * (1 << lg_delta) + * (1 << lg_base) + 2 * (1 << lg_delta) + * (1 << lg_base) + 3 * (1 << lg_delta) + * ... + * (1 << lg_base) + SC_NGROUP * (1 << lg_delta) [ == (1 << (lg_base + 1)) ] + * + * ... + * + * Regular group N: + * - Count: SC_NGROUP + * - Sizes: + * (relative to lg_base of LG_QUANTUM + SC_LG_NGROUP + N and lg_delta of + * lg_base - SC_LG_NGROUP) + * (1 << lg_base) + 1 * (1 << lg_delta) + * (1 << lg_base) + 2 * (1 << lg_delta) + * (1 << lg_base) + 3 * (1 << lg_delta) + * ... + * (1 << lg_base) + SC_NGROUP * (1 << lg_delta) [ == (1 << (lg_base + 1)) ] + * + * + * Representation of metadata: + * To make the math easy, we'll mostly work in lg quantities.
