Add notices to man pages and help strings cautioning against running
bytecode signatures from untrusted sources.
Also adds missing BytecodeUnsigned option to clamd.conf.sample files.
Add clamd config option to force blocking clamd database reload to
conserve RAM. Users may set `ConcurrentDatabaseReload no` in their
clamd.conf config file to force a blocking reload.
The blocking mode will still perform the reload in a new thread, but
will first free the current database, wait for scans targeting that
database to complete, and then load the new database in the new thread
and wait (`pthread_join()`) on that thread. Once loaded, any pending
scans will continue. This is effectively the same behavior as how
clamd reloads worked before the multi-threaded database reload feature
was added.
Add Data-Loss-Prevention option to detect credit cards only, excluding
debit and private label cards where possible.
You can select the credit card-only DLP mode for clamscan with the
`--structured-cc-mode` command-line option.
You can select the credit card-only DLP mode for clamd with the
`StructuredCCOnly` clamd.conf config option.
This patch also adds credit card matching for additional vendors:
- Mastercard 2016
- China Union Pay
- Discover 2009
This fixes issues in cvd download when network speed is slow.
Setting is passed to libcurl CURLOPT_TIMEOUT. Original default of 60s
was not enough if network speed is limited. Curl handles this as
total time for http(s) transfer.
https://curl.haxx.se/libcurl/c/CURLOPT_TIMEOUT.html
Also change commented out setting of ReceiveTimeout on example configs
to somewhat sensible value (1800s).

New features added to freshclam:
- Update signature definitions over HTTPS.
- Support for HTTP protocol v1.1 (formerly v1.0).
- New libfreshclam library with an all new API and versioning separate from libclamav (v2.0.0). This library is now build and installed alongside libclamav as a hard dependency of freshclam.
- The ability to opt-in and opt-out of standard and optional official ClamAV databases (ExtraDatabase, ExcludeDatabase)
- The option to specify the protocol and port number of official and private mirror servers.
- Support for additional types of proxy servers beyond plain HTTP (SOCKS 4, SOCKS 5).
Features removed from freshclam:
- Mirror management (mirrors.dat) file. This feature is no longer needed as official signature databases are distributed using a paid content delivery network (Cloudflare).
This commit also adds the following features for Windows users:
- The clamsubmit tool.
- The json-c library dependency, which will enable the --gen-json option in clamscan.
- Third party libraries under the win32/3rdparty directory have been removed. Developers will need to build the libraries separately from ClamAV and provide the headers and lib/dll library files the same way they do for OpenSSL. This includes libxml2, pthread-win32, bzip2, zlib, pcre2 as well as new dependencies: curl, json-c. Developers are encouraged to use the build tool Mussels to simplify this task.
