phabricator: add addadded function This is the most complicated part of the new code, and is responsible for adding all added files, whether brand new, copied, or moved. This also includes creating the phabchanges for the original files that have been moved or copied from, since they might need their awayPaths and type updating if multiple copies are involved.

sidedatacopies: directly fetch copies information from sidedata When using the sidedata mode, we don't need a complicated and expensive `context` object. Instead we directly fetch copies information from the sidedata (through a changelogrevision object). More optimisations coming. revision: large amount; added files: large amount; rename small amount; c3b14617fbd7 9ba6ab77fd29 filelog: ! wall 3.679613 comb 3.680000 user 3.580000 sys 0.100000 (median of 3) base: ! wall 8.884369 comb 8.880000 user 8.850000 sys 0.030000 (median of 3) before: ! wall 4.681985 comb 4.680000 user 4.640000 sys 0.040000 (median of 3) after: ! wall 3.955894 comb 3.950000 user 3.940000 sys 0.010000 (median of 3) revision: large amount; added files: small amount; rename small amount; c3b14617fbd7 f650a9b140d2 filelog: ! wall 0.003357 comb 0.010000 user 0.010000 sys 0.000000 (median of 781) base: ! wall 12.398524 comb 12.400000 user 12.330000 sys 0.070000 (median of 3) before: ! wall 6.459592 comb 6.470000 user 6.390000 sys 0.080000 (median of 3) after: ! wall 5.505774 comb 5.500000 user 5.410000 sys 0.090000 (median of 3) revision: large amount; added files: large amount; rename large amount; 08ea3258278e d9fa043f30c0 filelog: ! wall 2.754687 comb 2.760000 user 2.650000 sys 0.110000 (median of 4) base: ! wall 1.423166 comb 1.420000 user 1.400000 sys 0.020000 (median of 8) before: ! wall 0.961048 comb 0.960000 user 0.940000 sys 0.020000 (median of 11) after: ! wall 0.882950 comb 0.880000 user 0.880000 sys 0.000000 (median of 11) revision: small amount; added files: large amount; rename large amount; df6f7a526b60 a83dc6a2d56f filelog: ! wall 1.552293 comb 1.550000 user 1.510000 sys 0.040000 (median of 6 base: ! wall 0.022662 comb 0.020000 user 0.020000 sys 0.000000 (median of 128) before: ! wall 0.021649 comb 0.020000 user 0.020000 sys 0.000000 (median of 135) after: ! wall 0.020951 comb 0.020000 user 0.020000 sys 0.000000 (median of 141) revision: small amount; added files: large amount; rename small amount; 4aa4e1f8e19a 169138063d63 filelog: ! wall 1.500983 comb 1.500000 user 1.420000 sys 0.080000 (median of 7) base: ! wall 0.006956 comb 0.010000 user 0.010000 sys 0.000000 (median of 392) before: ! wall 0.004022 comb 0.000000 user 0.000000 sys 0.000000 (median of 735) after: ! wall 0.003988 comb 0.000000 user 0.000000 sys 0.000000 (median of 736) revision: small amount; added files: small amount; rename small amount; 4bc173b045a6 964879152e2e filelog: ! wall 0.011745 comb 0.020000 user 0.020000 sys 0.000000 (median of 250) base: ! wall 0.000156 comb 0.000000 user 0.000000 sys 0.000000 (median of 17180) before: ! wall 0.000118 comb 0.000000 user 0.000000 sys 0.000000 (median of 19170) after: ! wall 0.000097 comb 0.000000 user 0.000000 sys 0.000000 (median of 27276) revision: medium amount; added files: large amount; rename medium amount; c95f1ced15f2 2c68e87c3efe filelog: ! wall 3.228230 comb 3.230000 user 3.110000 sys 0.120000 (median of 4) base: ! wall 0.997640 comb 1.000000 user 0.980000 sys 0.020000 (median of 10) before: ! wall 0.679500 comb 0.680000 user 0.680000 sys 0.000000 (median of 15) after: ! wall 0.596779 comb 0.600000 user 0.600000 sys 0.000000 (median of 17) revision: medium amount; added files: medium amount; rename small amount; d343da0c55a8 d7746d32bf9d filelog: ! wall 1.052501 comb 1.060000 user 1.040000 sys 0.020000 (median of 10 base: ! wall 0.214519 comb 0.220000 user 0.220000 sys 0.000000 (median of 45) before: ! wall 0.149675 comb 0.150000 user 0.150000 sys 0.000000 (median of 66) after: ! wall 0.130786 comb 0.130000 user 0.130000 sys 0.000000 (median of 75) Differential Revision: https://phab.mercurial-scm.org/D7072

copies: use an unfiltered repository for the changeset centric algorithm Since the algorithm work form heads to ancestors, we don't need to check filtering for anything but the two entries. Using an unfiltered version is noticeably more efficient.

copies: extract data extraction into a `revinfo` function The function is build once at the beginning of the algorithm and used fetch appropriate information for each revision. This abstracts some implementation details from the main algorithm and will help us to access the data more efficiently in future changesets.
