Big update to LTS release process
  * Add create_lts.py script to to the LTS modification
    This is simpler than copybara since very few changes are needed
  * Use the default installation paths instead of a versioned path.
    If a versioned path is needed, this is easy to change on the commandline.
  * Make the integration test use the LTS transformed version
  * Test both static and dynamic linking (fixes pkg-config dynamic linking)

Move raw_hash_set::infoz_ into raw_hash_set::settings_. This reduces the size of raw_hash_sets by alignof(size_t) bytes when hashtablez is disabled.

Accept e.g. ".__uniq" as a valid clone name.  Further, bring the implementation
on par with libiberty's demangler grammar.

Clang introduced option -funique-internal-linkage-names that adds the suffix
".__uniq.[0-9]+" to internal linkage functions to give them a globally unique
identifier.  The suffix was designed to work with existing demanglers which do
recognize a "_" along with the alphanumeric string. This change enhances the
demangler to allow "_" with the alphanumeric string.

Please refer to libiberty's cp-demangle.c where function d_clone_suffix
implements the demangling of clone suffixes :

1.  '_' is accepted as a valid character with the alphanumeric sequence.
2.  The alphanumberic sequence is optional.
3.  The digit sequence is optional.

Clarify the comment on ABSL_CACHELINE_SIZE to indicate that the macro definition itself shouldn't change, but rather that call sites should change when possible.

This addresses the request for improved documentation in https://github.com/abseil/abseil-cpp/pull/842.
