codesearch: deduplicate $git->{nick} field
While PublicInbox::Config is responsible for some instances of
setting $git->{nick}, more PublicInbox::Git objects may be
created from loading the cindex and we should do our best to
reuse that memory, too.
I may be mistaken, but I suspect the reason jemalloc handles
long-lived processes better than glibc is due to granularity
reduction being scaled to larger size classes. This can waste
20% of an individual allocation, but increases the likelyhood
of reuse (without splitting/consolidating into other sizes).
In other words, glibc seems to try too hard to make the best fit
for initial allocations. This ends up being suboptimal over
time as those allocations are freed and similar (but not
identical) allocations come in. jemalloc sacrifices the best
initial fit for better fits over a long process lifetime.

www: use a dedicated limiter for blob solver
Wrap the entire solver command chain with a dedicated limiter.
The normal limiter is designed for longer-lived commands or ones
which serve a single HTTP request (e.g. git-http-backend or
cgit) and not effective for short memory + CPU intensive commands
used for solver.
Each overall solver request is both memory + CPU intensive: it
spawns several short-lived git processes(*) in addition to a
longer-lived `git cat-file --batch' process.
Thus running parallel solvers from a single -netd/-httpd worker
(which have their own parallelization) results in excessive
parallelism that is both memory and CPU-bound (not network-bound)
and cascade into slowdowns for handling simpler memory/CPU-bound
requests. Parallel solvers were also responsible for the
increased lifetime and frequency of zombies since the event loop
was too saturated to reap them.
We'll also return 503 on excessive solver queueing, since these
require an FD for the client HTTP(S) socket to be held onto.
(*) git (update-index|apply|ls-files) are all run by solver and

There's no need to recurse and trigger deep recursion warnings
when we hit a coderepo with a known hash (SHA-1 vs SHA-256).
Noticed while pruning the 1200+ repos on a git.kernel.org
mirror.

t/cindex: fix test when worktree PWD is a symlink
Our code aims to respect $ENV{PWD} (and therefore symlinks) as
much as possible to ensure portability across devices when repos
and indices are on portable or shared storage. Thus we can't
rely on Cwd::abs_path and ought to favor File::Spec->rel2abs
whenever absolute paths are required.
I noticed this when working on a VM where my worktree is a
symlink to a more reliable device.

cindex: index full (40/64 char) hex blob OIDs
This future proofs the index against git auto-abbreviation
needing more characters as the repo grows. It'll be useful for
joining against inboxes using dfpre.
As with emails, we'll continue indexing abbreviated blob OIDs
down to 7 hex characters so a SHA-1 git repo will have all
abbreviations of the OID from 7-39 hex characters in addition
to the 40 character unabbreviated form.

t/xap_helper: make sendmsg errors more obvious
By ignoring SIGPIPE, we hit our own error path and emit an informative
error message instead of dying abruptly and requiring somebody to run
`echo $?' to see the child status from their shell.

codesearch: use retry_reopen for WWW
As with mail search, a cindex may be updated while WWW is
serving requests. Thus we must reopen the Xapian DB when
the revision we're using becomes stale.

inbox: shrink data structures for publicinbox.*.hide
We no longer vivify the intermediate $ibx->{-hide} hashref,
instead we use $ibx->{-hide_$KEY} directly. This avoids
an intermediate hashref and extra hash table lookups.

www_listing: support publicInbox.nameIsUrl
This is a convenient (and slightly memory-saving) alternative to
specifying a `publicinbox.*.url' entry for every single inbox
when using publicinbox.wwwListing.
