[PATCH v6 0/2] fetch-pack: redact packfile urls in traces

["Ivan Frade via GitGitGadget" <gitgitgadget@gmail.com>]

Changes since v5:

 * Use hexsz instead of hardcoded hash sizes

Changes since v4:

 * Use "uri" instead of "url"
 * Look specifically for a line with packfile-uri format (instead of for a
   URL in general)
 * Limit the redacting to the packfile-uri section in do_fetch_pack_v2
 * Use "%.*s" instead of duplicating parts of the string to print

Changes since v3:

 * Enable redacting URLs for all sections
 * Redact only URL path (it was until the end of line)
 * Redact URL in die() with more friendly message
 * Update doc to mention that packfile URIs are also redacted.

Changes since v2:

 * Redact only the path of the URL
 * Test are now strict, validating the exact line expected in the log

Changes since v1:

 * Removed non-POSIX flags in tests
 * More accurate regex for the non-encrypted packfile line
 * Dropped documentation change
 * Dropped redacting the die message in http-fetch
