This now includes hosts with custom ports (and other hosts with the
same key), and explicitly excludes negated hosts, those with a
wildcard and those with an `@`-marker (e.g. `@revoked`)
It's also possibly a bit quicker because the ordering is better,
especially for files with many comments.

The type cached_esc_sequences_t caches escape sequences, and is tasked
with finding an escape sequence that prefixes a given string. Before
this fix, it did so by storing the lengths of cached escape sequences,
and searching for substrings of that length. The new implementation
instead stores all cached escape sequences in a sorted vector, and uses
binary search to find the shortest escape sequence that is a prefix of
the input. This is a substantial simplification that also reduces
allocations.
56d9134534 contained an LRU cache plus
changes to the documentation; 95162ef19d
reverted both.
This commit re-adds the documentation changes, which are still correct.
This eliminates the "missing" notion of env_var_t. Instead
env_get returns a maybe_t<env_var_t>, which forces callers to
handle the possibility that the variable is missing.
maybe_t is an implementation of the Maybe/Optional type, allowing
for an optional value to be stored. This will enable a more
principled approach for functions that return values or failure,
such as env_get.
This commit backs out certain optimizations around setting environment
variables, and replaces them with move semantics. env_set accepts a
list, by value, permitting callers to use std::move to transfer
ownership.
Commit f872f25f introduced a freed memory access regression on line 460
of env.cpp, where an environment variable was converted to a temporary
string, the .c_str() address of which was stored while the string
temporary was destroyed.
This commit keeps a reference to the original string lying around so
that the c_str() pointer does not point to freed memory.
Valgrind warns that the sometimes uninitialized sigaction.sa_flags field
is sometimes used when passed to the signal handler.
This patch explicitly zeros out the sigaction.sa_flags field at creation
time.

Fixes#4353 (regression in indexing of history contents) and introduces
new unit tests to catch bad $history indexing in the future.
